S1·E26 Chiros' Child

Lua falls into a trap set by the demon Chiros and falls into a fissure deep into the earth. A mysterious young girl treats Lua's wounds and leads her to a cavern containing the secret Chamber of the Thirteen Shamans. Lua is attacked by Apbats, but is saved by the Shamanic powers of the girl. Reading the Chamber's ancient hieroglyphics, Lua becomes convinced that the young girl is Zara, the Child Shaman of Lua's ancestors. They are attacked by Chiros' lava men, but rescued by the arrival of Jason, Tann, and Kong. Escaping to the surface, Lua is determined to show Zara all the secrets of the Island Shamans. Lua is about to give her the Primal Lightning Stone, when Zara's disguise is pierced revealing herself to be Chiros' chief servant Harpy. Harpy uses the Stone's powers to batter Kong, but is defeated by Lua's Shaman powers.
