Contrary to the beliefs of some, Tiamat was not slain by Marduk, but the substance that was Tiamat transmogrified into all creation and she was relegated to exist beyond the Ayin Soph Aur behind the Great Gate in the North. The cicadian rhythm of natural cycles teaches us to understand that day follows night and seasons change. How great is the difference in cosmic seasons? Is it like day and night? Or is it like the difference between cold and hot? Is Tiamat a demon? Is Tiamat a dragon? Look to your wife or mother. That is Tiamat, know that and take heed.
It seems that Tiamat appears in some sort of fictional form now and then, and that she's usually a dragon. *shrugs*
