Tiamat

Tiamat (pronounced tee-a-maht ), also known as the Nemesis of the Gods, was the queen of evil dragons and a servant of the greater god Bane. Like most other draconic deities, she was the offspring of the dragon creator deity Io. Tiamat was also the eternal rival of her brother Bahamut, ruler of the good metallic dragons.

Appearances
Tiamat had one head for each primary color of chromatic dragon (black, blue, green, red, white), and each head had the powers of a member of the respective race of dragonkind.

Worshipers
Tiamat had a reputation amongst the people of the new state of Unther for battling with the other members of their pantheon and was blamed for every one of the many setbacks Unther experienced.



Relationships
Being a member of certain pantheons made her some enemies, including Bane and Ilmater.

Having once been an archdevil living on Avernus, Tiamat was loosely allied with Bel and lent him many Abishai to fight in the Blood War. She resented Mammon for converting some evil dragons away from her. She helped Asmodeus forge his Ruby Rod but it was unknown what opinion either held of the other. Her aspects were also known to work with those of Kurtulmak.

She was the antithesis of her brother Bahamut, although some said that her hatred of him was also full of lust for the platinum dragon.

History
Tiamat was one of the children of Io and therefore a member of the draconic pantheon. Her worship began after the Tearfall which coincided with the arrival of dragons on Toril. Around 1,000 years later, individual dragons and dragon clans ruled great swathes of territory on Toril and this rulership was uncontested for a further 6,000 years. During this Time of Dragons, all draconic creatures were devout in their belief of the supremacy of one particular member of the draconic pantheon over all others. These holy wars were a fact of life for dragon-kind during the Time of Dragons and dragons died in huge numbers. Eventually, seeing the destruction that they had wrought on their own species in the name of deities who were supposed to be protecting them, most dragons abandoned the worship of their gods.

However, the hatred that had developed between Tiamat, Bahamut and their followers was so intense that they refused to stop fighting. The Dragonfall War as it came to be known, allowed giants to conquer some dragon territories and the ensuing conflicts also led to the rise of humanoid civilisations, especially those of the elves, whose mages created the Dracorage mythal which periodically forced all dragons to go violently insane. This marked the end of the Time of Dragons and the humaoids never allowed dragons to regain as much power as they once held.

In -2087 DR the Untheric pantheon was brought to Toril when the Imaskari planar barrier fell. Among them, a lesser 3-headed version of Tiamat and a god named Marduk who was an aspect of Bahamut. Now that they had humanoid worshipers, the Dragonfall War entered into a new period of intensity and over the next thousand years, the two gods placed more and more of their divine essence into their lesser aspects. Tiamat also worked against the other Untheric gods, with the result of the church of Enlil naming her the "Nemesis of the Gods" and blaming her for every problem the nation encountered.

Then, in -1071 DR, during the Orcgate Wars, Tiamat spied an opportunity to slay Gilgeam while he was completely occupied battling Ilneval. However, Marduk intercepted her and in the ensuing fracas, they killed each other. All of that divine power that had been focused in those mortal forms was lost. Tiamat was reduced from greater deity to the status of an archfiend, her last few followers in Unther not enough even to allow her to remain as a lesser deity.

This state of affairs lasted until 1346 DR when some Untherite cultists managed to summon another aspect of Tiamat to Toril. This aspect, known as the Dark Lady, formented rebellion all over Unther against the church of Gilgeam. Gilgeam was so hated that the membership in her own church swelled. She also took the opportunity to influence the lich Sammaster into tracking down the Dracorage mythal.

During the Time of Troubles, the Dark Lady was transformed back into her three-headed Untheric avatar which was promptly slain by Gilgeam's. Her divine essence though was somehow divided into three and came to inhabit Tchazzar, Gestaniius and Skuthosiin, three powerful chromatic dragons. Tchazzar devoured the other two, combining the three essences and ushering in the reappearance of Tiamat's more powerful five-headed form, which she used to kill Gilgeam and therefore cause Ao to dissolve the Untheric pantheon completely.



Re-taking a place as a lesser deity of the draconic pantheon in the wake of the Time of Troubles, Tiamat was able to manifest avatars once more but not a year had passed until one of them was destroyed by King Gareth Dragonsbane who had been tasked by Bahamut to destroy the Wand of Orcus in her heartsblood. Having done so, the king of Damara also brought the worship of Bahamut back to his people, elevating Bahamut to the status of lesser deity of the Faerûnian pantheon and re-kindling the Dragonfall War once more.

Tiamat joined the Faerûnian pantheon too in 1371 DR after gaining the worship of a cult in Luthcheq. She projected her wishes through the transformed primordial Entropy and in this guise, expanded her base of humanoid worshipers. She also sent many of her draconic servants to Vaasa to make trouble for the Church of Bahamut in Damara.

A race was on between her and Bahamut to gather worshipers to increase their powers before the Dragonfall War was truly joined once more. Tiamat started with the upper hand in this endeavour, being a deity of two pantheons and her nefarious plans were starting to come to fruition.

In 1373 DR Sammaster had managed to alter the Dracorage mythal to cause permanent insanity in all dragons, unless they allowed themselves to become dracoliches. In one of the worst dracorages ever seen on Toril, Tiamat resurrected Tchazzar, Gestaniius and Skuthosiin to act as emissaries which she would use to solidify and expand her power base in Chessenta, Mulhorand, Threskel and Unther.

Sammaster and the Dracorage mythal were destroyed by adventurers and dragonkind all over Toril soon realised that the Time of Dragons could once more be a reality. This coincided with a great storm, after which thousands of dragon-like eggs were discovered. Tiamat instructed her followers to find and collect as many of these eggs as they could. They obeyed and more than half of the total number of eggs were brought to Unthalass where they began to hatch.

Tiamat spent her new forces mostly in her efforts to conquer the east but that task proved more difficult than she envisioned. Only Tchazzar met with success, cementing his rule in Chessenta while Unther was conquered by Mulhorand. Her tentative ally Alasklerbanbastos also ruled Threskel and allowed Tiamat's church to establish a stronghold there. A short-lived but powerful cult of humanoid fanatics was also lost to her in the Wyrmbones.

Her losses outweighed her gains however: Entropy ceased being a simple vessel for communication and spells, taking away her power base in Luthcheq. Tchazzar managed to conquer Threskel for himself but this just drew him into a war with the Abeiran nation of Tymanther where he was killed.

With her most powerful servant dead, her forces beginning to crumble and Bahamut's power increasing after he replaced Tyr as the god of justice, Tiamat decided to pledge herself to serve Bane and the Dragonfall War stalled, possibly never really to be rekindled.

Dogma
Rival deities of all creeds and from every pantheon are inherently tyrannical. They seek only power, at any cost, despite their honeyed words. The Dragon Queen is the only being powerful enough to defy the gods and overthrow their despotic rule, as demonstrated by her overthrow of the other Untheric deities. Work tirelessly toward the day when Tiamat will banish the gods from Faerûn and unite the world under her rule. Toward this goal, follow her commands unquestioningly and be willing to sacrifice yourself in her service. To overthrow the gods requires power, and power is acquired through the accumulation of wealth and magic. Power demands respect. Chromatic dragons everywhere are to be venerated as the spawn of the Dragon Queen and paid homage. When Tiamat assumes her throne, her draconic children shall serve her as dukes, and her clergy as their mortal vassals.

Inconsistencies
The adventure The Throne of Bloodstone depicts Tiamat being slain by Gareth Dragonsbane and his party, on the instructions of Bahamut as her heart was needed to destroy the Wand of Orcus. As originally written this adventure took place in 1148 DR: too early for Dragonsbane to be included in the modern Forgotten Realms. The date was thus retconned and the death of Tiamat has not been mentioned since, although the destruction of the wand is still a canonical event.

Faiths and Avatars suggested several theories for the survival of Tiamat: that the actual dragon slain was actually Takhisis (a deity from a different Crystal Sphere), that a deity can only truly be slain on their home plane (unless they are stripped of their divinity, as happened during The Time of Troubles) and so Tiamat simply reappeared in Dragon Eyrie, or simply a different multi-headed dragon or even an imposter.

Dragons of Faerûn states the Dragonsbane party destroyed an avatar of Tiamat. Although Tiamat's avatar was also slain by Gilgeam, this indicates the death of the avatar did not destroy Tiamat herself but merely slowed her plans for a time.
