Tiamat

Okay, so imagine you are playing a game and you are the main character. You have to fight different bosses to win the game, right?

Well, Tiamat is like a boss in a game. But instead of a game, it is a character from mythology. In ancient Mesopotamian mythology, Tiamat is a goddess of chaos and the sea.

So basically, Tiamat is a really powerful creature from ancient Mesopotamian mythology and is often portrayed as a dragon or serpent with many heads.
