Master of Kobolds in a doomed world
Great Wyrm Red Dragon
Oddly not Evil and apparently not chaotic either.
She is worshipped by her kobolds who are remarkably efficient at managing her affairs and keeping track of her treasure.
When the sky broke and the invaders showed up, she escaped with her kobolds and most of her treasure to the grand citadel above her lair. There she is hoping to find the lost pieces of an ancient artifact she had in her horde but suspects have been taken by the four beings who arrived shortly after the sky started to consume reality.
