Rise of the Demon Lord
- Koyas, or Koyas the Mad, was a Monk who appeared to be a homeless human roaming the streets of Mithrendain.
- He had been part of an adventuring group who had assaulted the Black Guard. The group fled, but he was captured.
- His mind had apparently been broken as a torture victim of the Black Guard.
- Koyas could have a timid personality one minute, brutish the next.
