Time Taken: One round or longer.
Alien Species involves knowledge of any species outside of the character's. For human characters, it covers all non-humans; for Wookiees, the skill covers all non-Wookiees.
Alien Species represents knowledge of customs, societies, physical appearance, attitudes, philosophy, history, art, politics, special abilities, and other areas of reasonable knowledge.
Note: Alien Species determines what possible languages a character can learn.
