The orcs’ five High Clerics serve as the prophets of their god, and are generally regarded as the wisest and most respected members of orc culture. Any orc, male or female, can become a High Cleric, though the process is incredibly arduous.
Once an orc gladiator wins 100 arena battles in row (an astoundingly difficult feat that can only be remotely accomplished by the most ferocious and intelligent combatants), the orc must enter the Cave of Subjugation, an utterly lightness and tiny cavern deep within the mountain. The gladiator must meditate in darkness, alone, for 100 days. When the orc emerges from the cave, he or she must then challenge one of the current High Clerics in single combat to the death. If the challenger wins, he or she becomes the High Cleric in place of the one they defeated.
