She was created alongside her "brother" Bahamut when the Primordial Erek-Hus slew Io, the father of Dragons. Rising from the corpse of her "father", she and Bahamut destroyed the Primordial, before turning on each other. Where Bahamut represents the nobility and sense of justice his father had, Tiamat represents his other characteristics: avarice, pride, arrogance, and the raw power to get away with it. Unlike her one-headed brother and two-headed father, Tiamat has five heads, with each head being of a different color (White, Black, Green, Blue, and Red). She has the abilities of all of the chromatic dragons, with each head able to use its associated breath weapon, on top of her immense physical size and a massive, sting-tipped tail, like that of a Wyvern.
She is a vain, greedy, lustful and arrogant goddess, expressing what would be extreme hubris if she wasn't already a god. Though she is a paragon of dragon strengths, she shows few of their weaknesses; she is not impatient, nor overconfident (when dealing with other gods). Her primary concern is the propagation and well-being of chromatic dragons as a whole, ensuring her children become owners of the world. She believes this goal necessarily requires overthrowing the rule of Bahamut and establishing supremacy over metallic dragonkind. Like Anonymous, Tiamat never forgets and does not forgive. Although she is not adverse to occasionally burning a village to the ground for the lulz, Tiamat is not exactly an up-front goddess; she is a long-term plotter and schemer, carefully manipulating others in Tzeentchian plots that are so subtle and so long-reaching that an enemy would likely find themselves unprepared even if they had foreknowledge of what she had planned years in advance, making her a deity of Just as planned.
Tiamat lives in the astral domain of Tytherion, a realm shared with Zehir. Her realm is Azharul, located in ravines and hewn out in the rock of Tytherion. Why the goddess of dragons lives underground and the lord of serpents in the highest reaches of the domain is the story of how Tiamat set up her realm. After her defeat at the hands of Bahamut, Tiamat took a liking to Tytherion and set up shop there, chasing Zehir's followers to their bastions and temples, large buildings build above ground, leaving Tiamat with the rest. Though they wage no open war, Tiamat is constantly scheming against Zehir, planning on claiming the domain for herself one day.
Tiamat's first and foremost servants are the chromatic dragons. About 95% of them serve their goddess in some way. Those who prefer a different deity have a grim fate waiting for them: in the depths of her lair behind a pair of 100' adamantine doors Tiamat has a collection of the souls of those chromatics sworn to other deities, locked up for eternity. Tiamat has recently begun to create the Spawn of Tiamat in notable numbers, who are born from the eggs of dragons instead of the regular wyrmlings, or from two Spawn of the same kind mating. Dragons who sire the Spawn of Tiamat consider it a good omen and a sign of Tiamat's favor to have part-dragon monsters born instead of their own children born from their eggs. These are divided into five groups, based on their color: the Blackspawn who consist of strong raiders (and one type looking like spiders for some reason), the Bluespawn who are mostly unintelligent beasts of war, the Greenspawn who are small(ish) ambushers who work best in forest and swamp environments, the Redspawn who are the Spawn's primary source of magic (fire magic of course), and the Whitespawn who gather in large numbers and excel at fighting in cold environments and clan warfare.
Aside from the Chromatics and Spawn, Tiamat counts a notable number of humanoids amongst her servants, mainly Dragonborn and other part-dragons, and Humans. Most Kobolds worship individual dragons as gods, but the smarter ones who know about Tiamat might turn a tribe to her worship instead. The Queen of chromatic dragons demands reverence, homage, supplication, and tribute from her subjects. As a dragon, her hoard is believed to be worth trillions.
Another thing of note is that Tiamat "likes" to "give audience" to mortals in her "inner sanctum". In other words, Tiamat likes her some non-divine dick. Most of the time this means she fucks a chromatic that impressed her, but she's also known to have courted catastrophic, metallic, planar and scourge dragons. Amongst her current fuckbuddies is a Dragonborn, though it's not mentioned if she takes her human shape before having sex with humanoids.
- In Advanced Dungeons & Dragons, Tiamat first appears as a unique boss-monster in the Greyhawk setting. Later, she has the first layer of the Nine Hells assigned to her as her 'home plane,' giving her Outsider status and the ability to avoid permanent death.
- In the Dungeons and Dragons cartoon, she was powerful enough to kick the shit out of both the Dungeon Master and the Venger, the show's main antagonist, giving you a general grasp of how goddamned powerful she is.
- When she feels the need to deal with mortals, she typically assumes the form of an exquisitely beautiful dark-haired human sorceress.
- In the Dragonlance setting, the goddess of evil stuff "Takhisis" uses a Tiamat form as her avatar and is essentially a slightly tweaked version of her.
- In AD&D 2nd edition, the Forgotten Realms campaign setting has a religion dedicated to her.
- In D&D 3rd edition, she's pretty much still the same, though she favors her natural, five-headed form.
- In D&D 4th edition, she is no longer considered a unique type of dragon, but always referred to as a goddess who happens to have a draconic primary avatar.
- In Dungeons & Dragons 5th Edition, her cult in the Forgotten Realms attempts to bring her back to Faerun from the Nine Hells, which is the focus of the first major storyline, "Tyranny of Dragons". If your players really fuck up, the cult could even succeed. In a lot of ways this version is like the Dragonlance Takhisis, because if she actually succeeds and returns to Faerun, the first thing she does is eat all the Cult of the Dragon cultists and humiliate their leader Severin, who brought her back - despite them worshipping her - just because she feels like being a dick, again.
