Yotgha is a plant that exists in the Halls of Horror, deep below the Scarlet Citadel. The plant has unnaturally red leaves, almost glowing. It held the wizard Pelias for ten years after he was captured by Tsotha-lanti, drawing all intelligence and consiusness from him. Pelias was freed from the plant by Conan who was also captured by Tsotha, by Conan cutting the stem of the flower. According to Pelias, the root of the plant is set in hell.
