"A lizard... or a dragon? The girl stands perplexed before you, seemingly unsure as well about certain aspects of yourself. The surprise of the noise instinctively placed your hand on your weapon but the dragon - or lizard -girl seems to have no intention of launching any attack."
A daughter of what must be assumed an uncorrupted Champion of Mareth, Tiamat was accidentally cast into the Gaia's world by one of the many portals in her home.
Her name derives from the ancient Mesopotamian religion (Sumerian, Assyrian, Akkadian and Babylonian), where Tiamat is a primordial goddess of the ocean, generally described as a dragon or sea serpent.The Enûma Elish states that Tiamat gave birth to dragons and serpents among a more general list of monsters, which is her link to ancient mythology in the World of Gaia, where the Player Character can take on the role of her mate in the breeding of dragons.
