Goblins

Reference: http://reality-smiths.com/brotherhood/codex/denizens/goblin.html

Goblins are nasty scavengers. Everything they own or work with they either discovered or stole from somebody. Because of their lack of ingenuity, goblins are either found raiding towns, or in their lairs, which are typically primitive villages or damp natural caves. A solitary goblin is rarely a threat to even the most novice warrior, but their nature is to form clans and strike in groups. Wise adventurers, wary of that fact, avoid goblin settlements unless their numbers are also great.
