Vroolixar was a copper dragon wizard who deeply studied time magic. His various experiments with the Dragonclock allowed him to travel back in time and gift his own egg to his apprentice, Chimi Chagna beginning a paradoxical loop.
The older version was murdered by the sorcerer Eilara Shay just after his younger self hatched from an egg and served as Chimi Chagna's familiar and apprentice. His various travels with fellow time traveler Gallione Shay had echoing and paradoxical effects on much of the events of the third, fourth, and fifth ages, and maybe more.
Vroolixar lived his life knowing the precise date and time of his death, causing him to have a melancholic attitude.
He lived in a secluded tower outside of the gnomish section of the town of An Lema.
