Well, from my knowledge of Dragonlance, Takhisis (I'm sure it's not Tiamat, Drakron) has three avatar forms. One is that chromatic dragon thing that Drakron mentioned, one is the dark warrior-her in human form with black armor on, and the other one is the seductress-you can guess that. I'm sure Tiamat exists in Faerun Drakron, but not in Dragonlance, at least at the time of the Chronicles Saga. And she doesn't have a lich form.
