Tropers / Falcor

Falcor is a corporeal, carbon-based organic life form of the XX chromosome persuasion. In her natural habitat, she may be lured by the promise of sushi, shiny new dvds, and books about odd topics. She is left-handed, which puts her in the 10% percent of the world population technically operating in their right mind. She is allergic to pineapple, but doesn't hold it against them. She talks to herself on a regular basis, but herself doesn't always feel like answering.

She may or may not be a time traveler.
