Description Goblins are small, black-hearted humanoids that lair in despoiled dungeons and other dismal settings. Individually weak, they gather in large numbers to torment other creatures.
Personality Like other goblinoids, goblins often had a short temper, and were more easily provoked than individuals of most other races. They often found it difficult to overcome this short fuse, and had a sense of greed that made it difficult for them to act altruistically. They also generally took sadistic pleasure in exacting revenge once crossed.
Young goblins were taught from an early age to rely only on themselves, and that to survive, they needed to be aggressive and ruthless. To a goblin, it didn't seem logical to treat others as well or better than you would treat yourself; rather, they believed in preemptively removing potential rivals before they could become a threat. Expatriated goblins would sometimes try to recreate the circumstances of their culture, preying on the weaknesses of others in non-goblin communities.
Despite their generally poor reputation however, not all goblins were dim-witted or evil. Some goblins have risen to become heroes, gaining enough renown to be accepted into the civilized world of other, more commonly good races. Those goblins seeking this path may have found it difficult to overcome their temper and greed, as well as the cultural influence of their brethren, but those who did often found it could be more rewarding, in the long run at least, to serve good rather than to serve evil. Those that did often made use of their ill-gained talents as rogues or fighters.
