Goblins

Unlike their Orc cousins, Goblins are known to be weak and wiley. Often those that lives in a Orkin tribe are mistretad. Bullied for being weak, given the least pleasent tasks and get the last of scraps for food.

Those that survive are because they are cunning. Able to avoid the angry orc and steal what they need. It is not surprising that goblins have earned an untrustworthy reputation from the other races.

Costume
Goblins have green face paint and are known to have elongated and pointed ears or noses. They would wear similar and mute colour clothing
