Commentary from the sage in the Cage, who's all the rage:
It is difficult to obtain information about the deities themselves. Occasionally a deity will volunteer information about themselves or
another deity, but most onfo comes from watching priests and their rituals. No deity will willingly reveal that they are untrustworthy,
since they want followers.

Deities have worshippers. The mind of a deity is vast, and could contain several viewpoints.

Names: most deities have multiple names in different regions

Dividing line between immortals and gods:
It is quite difficult to determine, since the gods are called immortals by some people. There may not be a dividing line, since they may be one and the same. Since the agents of the gods are immortal, they are occasionally called immortals. The difference may be bassed on power, but also status, in that immortals work for gods. Perhaps they are all immortals, but not all gods. Often immortals do not have followers, or have small groups of followers. The discussion is somewhat academic, since it doesn't appear to make a difference. Except in the terminology of course.

Both gods and immortals appear to be limited in what actions they can perform on the prime material plane, including Mystara. They are under no such restriction on the outer planes, since means the gods are much closer to us here. I suspect if a god wanted to, they could wipe everything living thing off the face of the cage, in an eyeblink. That they haven't either means that they are restrained by other rules, or they have a sense of humor. The rules may be imposed from above, which gives rise to the interesting pholosophical question of who is the ultimate power in the universe. Or the rules may just be the equivalent of polite society.

Musings from the author:
Powers may be deities, it's not clear, they may be more primitive things. Rad is a power not a deity.

On gaining immortality, paperman said:
Immortals are less powerful than deities. To reach immortality you need to:

• find a sponsor
• petition at a particular site depending with a gift for the sponsor (an artifact would be appropriate)
• pass whatever tests the sponsor places upon you
• then undertake a quest on behalf of sponsor.

• Al-Kalim: No other names known. Known to be friendly with The Old * of the Sea. * represents whatever race the deity is known to. Followed mainly on Mystara, in several countries. Has an interest in water, water magic and combat. Known for his loyalty.
• Alphaks, The Destroyer: deity of giants and demons. Opposed to Alphatia. Arrived with Alphatia from the Alphatian Home System. Fought us bringing back Roland with a green glow. Was a giant deity, but lost. Speaks Alphatian, and tends to swear. It is illegal to worship Alpaks in Alphatia. Alphaks is unfriendly with everybody. No other names known. Not trustworthy at all. Most priests are demons, the really nasty kind who delight in random destruction. Probably insane. Certainly not trustworthy, unless you are more powerful thean him. The Gammarians have his shrivelled heart in a box.
• Alphatia: deity of painting and magic. Arrived with the Alphatian refugees from the Alphatian Home System. Followed almost exclusively in Alphatia itself, although she may be known by other names in other places. Her symbol is an artists palette. She is often considered a deity of peace as well as magic and the arts.
• Apollo: see Ixion. God of light and archery.
• Ares: apparently is Vanya. Worshipped in Thyatis. Vanya is also worshipped in Thyatis.
• Asterius: moon symbol. Patron of trade of the Minrathad, Ierendi and Thyatis trade guilds. Known to be unfriendly with Thanatos (reason unknown). Symbol varies, generally ships or wagons. Followers of Asterius tend to be fairly similiar, and surprisingly honest. Planar spiders seem to be all followers of his (they are great traders).
• Athena: also known as Freya. A deity of wisdom and battle. Enemy of Ares. Possibly two deities working in conjunction, because she seems to be a patron of two differing areas. (ie: physical and mental). Her symbol generally is a sword, spear or owl related. This deity has paladins, so is probably fairly trustworthy.
• Bemarris: deity of combat ... swords as symbol? Could be another deity under an assumed name. Not a high ranked deity. Sage never actually met a single follower of this deity.
• Bozdogand, The Deceiver: worshipped in Hule. Telling the truth is blasphemy! Only deity allowed in Hule. Bozdogand is Loki.
• Brissard: few priests. Largely a mystery.
• Chardastes: a vanishing religion. Healing deity.
• Church of Karameikos: found in Karameikos.
• Church of Traladara: found in Traladara (where is that?)
• Church, The People's: found in Ierendi
• Cretia: A deity found only in one country, the Ethengar Khanate. It's probably another deity, but sage doesn't know which one without further information.
• Demogorgon: nasty. A deity followed by the devils. Very evil, also seems to delight in destruction. Frighteningly, his destruction has purpose, plan and direction. That purpose is generally to cause more destruction. No specific symbol.
• Diamond: ?
• Diulanna: patroness of will. No known enemies. Often acts as a patron of adventurers. Has small followings across the planes. Her symbol is a spear thrust clean through a boulder.
• Djaea: Another druidical deity. Possibly the same name as various other druidical deities.
• Evendall: followed by elves in Alfiesh. Is Evendall Ilsundal under another name?
• Faerie: the faerie are deities who did not participate in the last god war and were cursed back to near mortality. The faeries can be invisible, and have a noble court. Faerie sight allows one to see faeries (some of us have it). Faerie include nymphs, dryads, and brownies. They have a long life and begin another one after they die. Brownies clean houses ... (Tess has seen brownies doing so, they were amazed that he could see them and ran away very afraid.). The biggest court of the Faerie is near the Alfheim border, near the lake - southwest from the town on the edge inside Alfheim. The court is ruled by King Oberon and Queen Y. The Faeries won't play a part in this world. Do the faeries play a part in other worlds? They view the world as going through cycles - the last cycle was the sphere of death, we are currently in the sphere of life. In the sphere of life, more deities represent life than death. Some of the surviving deities from the sphere of death, probably include Hel.
• Forsetta: Comes from the Northern Reaches on Mystara. Acts as the local deity of the old royal family. Perhaps he has some kind of relationship with them.
• Frey: very similar to Freya. Possibly part of a personality of Athena/Freya. Deity of the forest(?). Worshipped in the Northern Reaches.
• Freya: also known as Athena (Garal Glitterlode said this). She has said she is known by multiple names. Athena may also be Odin (doubtful, but sounds similar to both Vanya and Ares being worshipped in Thyatis). Freya was talking to a middle-aged person with black thinning hair, wearing robes. The person was complaining that he would lose worshippers if Freya went ahead with her plan, Freya said that would just have to be the case. Freya and Nyx are enemies. Deity of agriculture and the common people. Worshipped in the Northern Reaches.
• Gaea: a druidic deity. Probably another name for Terra. Never really seems to be much difference between them.
• Garal Glitterlode: deity of gnomes and tinkering. Garal Glitterlode seems not to have many friends or enemies.
• Hecate: deity of magic, powerful. Symbol is the full moon. Not a "hands-on" deity at all, tends not to intervene much in mortal affairs. Hecate seems to destroy those who stand in her way, but admires those with the strength to resist.
• Hel: allowed us to return with the husband of the Elvish witch, she was talking to a representative of/or Nyx at the time ... and Nyx was very angry - presumably at the torture of her priest. Hel had just been out on important business according to an old woman called Senility ... she mentioned something about a city Pandas (get someone to research this) and a guy called Yorg - who got out with the help of friends who made a deal with Hel. Deity of the dead (Northern Reaches). Is Hel the same as Thanatos? Hel's priests tend to be cool, calm and collected. Hel is also the deity of reincarnation and rebirth. Also known to be one of the deities with the most personal influence amongst other deities. Has many allies, including amongst those who are not normally considered evil.
• Hermes: deity of messengers. Mainly showy thieves, not those who steal for profit. Also acts as a minor patron of medicine and travel (which is really more Asterius).
• Idu, the Sun King: Sun god, the god of a race far down south, the Enduks. Probably is Ixion.
• Ilsundal: followed by elves in Alfheim, appears to be a great enemy of Rafiel. Very handsome, best at everything. Usually appears as an elf in rich robes. The main deity of elves. Friendly with Ixion, Djaea, Gaea. Seems to be the epitome of what an elf should be. Head of the Elvish pantheon. Worshipped also by the Callari elves, and probably in Wendar.
• Ixion: deity of the sun. Symbol is a flaming wheel, this was Rosaline's symbol. Probably is Idu. Ixion is called Apollo in Thyatis and related countries. One of the most powerful deities, with many followers across the planes. Not many in the cage tho :) Lover of Valerias. Known by many names, too many to mention. Also has paladins.
• Jammudaru: Minor deity of revenge. Often followed by various "monster" races (trolls, giants).
• Ka: Also called the Amber Serpent. Not many followers on any known plane. His priests are generally intelligent non-humanoids. Probably not especially powerful as deities go. The deity itself could be a dragon.
• Karassh: deity of orcs. Symbol is a three-pronged sword. Also acts as a patron of warfare and tactics. Not known by any other names. The patron of orcs, he may have created that race in his image.
• Khoronus: deity of time. Symbol is an hourglass. Deity of time. His priests are reputed to have the ability to travel in time, although this has not been confirmed. Quite mysterious.
• Korotiku: deity of puzzles and jokes. Symbol is a spider silhouette/shadow. Deity of pranksters. Beware of his priests! Couldn't trust him as far as you could kick him. His universal symbol is a spider silhouette.
• Koryis: deity of peace. Symbol is the outstretched palm of the hand. Trustworthy. Not very common in the cage. Occasionally acts as a patron of adventurers which act with their brains not their sword arms.
• Lady of the Noose, The: deity of assassination.
• Leptar: nasty. Followed by demons. Not very intelligent, not very highly ranked (even amongst the demons).
• Lighthaft, Sir: a relatively new deity. Has knightly followers. See also Morgan.
• Loki: worshipped by pirates in the Northern Reaches. Also known as Bozdogand. A deity of nasty tricks, pranks and theft. Deity of deception also.
• Lolth: deity of dark elves. Unfriendly to everyone, enemies with most deities. Probably has done something to offend them all.
• Lord: deity of the pegotaurs. Fought Alphaks when Safranna prayed to bring back Roland. Had a white glow.
• Morgan: a deity who started around the same time as Sir Lighthaft and closely allied. Deity of healing. Seems to be replacing worship of Chardastes. Athena is known to be close to them, the followers of Lighthaft and Morgan are often drawn from the ranks of (former) followers of Athena. They have similiar interests, and derive their followers mainly from the same countries tho, so this isn't too surprising.
• Noumena: deity of games (e.g. chess). Could be Korotiku by another name. Seems more fond of deeper thoughts than Korotiku, so maybe not.
• Nyx is getting badly nailed at the moment. Deity of Undead. Was the sponsor of Thasmodean, but they had a falling out several hundred years ago. Trying to create new forms of undead which can breed. Symbol is a white crescent on a black circle. Hasn't sided with giants in the past. Creates new types of undead and semiundead - for examples spirits which reproduce. Quite lawful. Her priests seek to create new and varied types of undead.
• Odin: deity of Wisdom. Leaders in the Northern reaches often worship Odin. Deity of leaders, symbol is a missing eye or eye patch. Odin appears to be one of the leaders amongst deities, possibly the leader of a significant faction. Commonly depicted with two ravens and a staff. Seems to be friendly with Frey(a), Loki, and Thor.
• Orcus: Another demon deity. Demons seem to think they differ, but me to me they seem all the same. I wonder if they say that about human deities.
• Ordana: Another nature deity. Maybe Terra by another name again? More a deity of the forest, and her symbols tend to reflect this, with trees and flowers.
• Pantheon, The: a group of deities: death, fire, war, peace etc ... in Sind.
• Rafiel: deity of the Shadow Elves. Member of the Brotherhood of the Radiance.
• Rathanos: deity of fire, energy and magic. Symbol is a manlike being of fire. Rathanos is probably a fire elemental with much much more. Worshipped in Alphatia. A patron of the element of fire. Probably a fire elemental, since he has so many followers amongst them. Holy symbol is a man shaped being of fire. Friendly with Ixion.
• Razud: a deity of magic, especially travelling mages.
• Shining One, The: worshipped by kobolds. Symbol is a polished breastplate. Fond of traps and tricks. Difficult to find any information about, quite sneaky. Possibly created the kobolds.
• Sif: Thor's wife. Deity of excellence.
• Ssu-ma: deity of knowledge. Temples are libraries. Deity of the written word and books. An ancient deity. Few followers. Friendly with Athena, Noumena. Tends to have scholars as followers.
• Talitha: thieve's guild deity, symbol is a screaming baby. Steal to hurt people. Not a deity to mess with. Often found in theives or assasins guilds. Unfortunately it is somewhat difficult for me to gain information about this deity, since I like to keep my body unventilated.
• Tarastia: deity of law. Symbol is an axe. Judge and executioner. Priests of Tarastia are often members of the Guvners, who administer the law. Don't ever, ever cross one of these priests. They can be downright nasty if crossed. Worshipped by lawyers.
• Terra: deity of gardening(?). Followers of Terra belive that her true body is Mystara. Followers on other worlds tend to say similiar things about their world. Symbols vary greatly, often just a round plain disk.
• Thanatos: deity of death. Thanatos is also one of the most powerful of deities. His area of concern is death and the undead. He appears as an undead style creature, carrying a scythe. He is known by many names thoughout the planes, but the scythe symbol appears to be a universal recognized symbol of death and Thanatos.
• Thasmodean, The Lord of Worms: had lots of power a few centuries ago. This may coincide with the Sundered Man.
• Thor: deity of berserkers, worshipped in the Northern Reaches. Somewhat friendly with the giants because they make good beer.
• Twelve Watches, The: deities of crafts which have banded together. A group of not especially powerful deities who seem to have banded together. Patrons of various crafts.
• Tyche: She is the patroness of luck and fortune. Often followed by those who place their lives at risk daily (ie: adventurers).
• Valerius: Moderately powerful deity. Her followers are not known for their personal power tho. Patroness of love and passion.
• Vanya is the goddess of conquerors and warriors. Popular in Thyatis (known as Ares there). Could be Ares, might not. In Thyatis, there are temples to both. Well known across the planes under this name tho. Symbol is mostly martial, depicting swords, spears and lances.
• Wayland: No followers that I am aware of. Often the creator of various relics (which may be thought to be the relics of various other deities). Reputed to wander prime worlds in mortal form.
• Zirchev the Hunter: protector of forest races. Worshipped by Orlan.
