 Goblins perform the bulk of manual labor needed by the orcs, with the sole exception of jobs that require the brute strength of true orcs. Those the orcs revel in as proof of their prowess."

 Almost every orc is a member of a tribe or a clan. Relations between neighboring tribes are usually violent, except in cases of a mutual enemy threatens their existence or prospects of great plunder override mutual animosity. Occasionally, a single strong chieftain may emerge to lead multiple tribes from time to time, usually through intimidation of followers. An orc tribe in times of peace tends to focus almost solely on strengthening itself in preparation for the next armed conflict. Orcs are known to possess a crude system of writing — usually in blood — although it’s most commonly used to trade insults or threats among tribal leaders.
