Rare Races

Races that are listed as Rare Races are those which, unless a specific reason in a character's backstory would justify their knowledge of that race, should be considered as completely foreign to a character. These are races that are rarely, if ever, seen by individuals outside their own race, and as such should be considered a complete enigma to a character until they have had experience in interacting with said race. If you encounter race X and do action Y because you know race X responds to action Y in Z way, that is absolutely meta-gaming and should be avoided.
