Tiamat

Tiamat was/is one of the original two dragons that supposedly created the earth and responsible for giving Dragons the ability to procreate with each other. How she was created is unknown. She was also the eternal rival of her brother Bahamut, who was said to be completely different to her.
== Lore ==
=== Tiamat, The Evil Dragon God ===
Tiamat was described as a Dragon Deity, with five great heads all of different colours and could breathe different elements depending on the head. Along with her brother Bahamut, they were the first known sentient life forms on Solara, leading to the rumours that they were the ones that created the world, but is largely unknown.
Tiamat was known to be a more sinister and evil dragon compared to that of her brother of whom was known to be wise and ruled in a good, kind but justified way. This led to the constant rivalry between the two as they both saw each other as the others better yet refused to get into any actual conflict over certain matters and instead ruled their Dragons in their own ways.
=== The Flame Appears ===
When the First Flame appeared, Bahamut pondered about the creatures that came from it and the Great Souls that were found inside, whereas Tiamat did not believe there was any threat, until Gwyn and the other wielders declared war on the Dragons for rule of the earth. Tiamat initially led the war against the Lords and Humanity with Kalameet as her second in command, destroying whole armies of Humans in the first years of the war, with Bahamuts army of dragons following suit a few years later. 
Bahamut however tried to make peace with Gwyn and tried to come to an understanding with them following the defection of Seath the Scaleless and the death of the Great Dragon Sinh. This greatly angered Tiamat to the point where she tried to sacrifice Bahamut and Gwyn subsequently captured him and bound him deep below the earth with ancient magic.
Tiamat, now the sole leader of the Dragon Army becomes over-enthralled with the power she now has and recklessly attacked the armies of Humanity with her entire force. What followed was a great massacre of both Dragons and Humans as the Great Souls combined their power. The Gravelord Nito unleashed a miasma of death and destruction. Gwyn conjured sunlight beams that ripped apart the scales of the Dragons. The Witch of Izalith weaved great firestorms that brought the dragons to their knees.
=== Imprisonment and Human Form ===
Tiamat was subsequently captured and Gwyn bound her deep below the earth just like he did with Bahamut. Her second in command Kalameet managed to flee the war along with some other dragons, though the Dragons were effectively decimated.
It has long been rumoured that whilst she was imprisoned, through some form of projection, Tiamat was able to take a female human form and wander the lands, causing minor disturbances and stirring trouble among the townsfolk across the world. These rumours however are long thought to be just that, rumours and no proof has ever existed since the spreading of them and is now deemed a myth. Some have also thought of her possibly being long dead, due to the fact that her and her brothers location of imprisonment being lost to time.
