The Orkens of the Titan Clan used to dwell in the high mountains. They would carve caves out of the rocks and store their young in them until they were reached maturity. Incidentally, Ugo'yash corrupted the underwater springs that supplied the caves, and now, as a reminder for all eternity, the fountains spout blood instead of water.
