Orcs don't like questions. Everybody with a brain knows that. Orc tribes save their strength for fighting, not thinking. They survive by raiding the lands of weaker races, repeating it year after year to offer tribute to the masters of their mountain home.
Life on Firebrand Peak is short and nasty. Death comes quickly and the fallen are soon forgotten. Generations pass, yet the tribe remains brutally the same.
Until one little orc starts asking too many questions.
