The hereditary position of Spirit Caller or tribal Shaman is a crucial one to the Nui, and has been passed down, from parent to child, for countless turns of the seasons. Mormo’s ancestor was the very first Shaman of the Water Moles of Rapa Nui, long before Skull Island was colonized by the powers of the Spiral. Mormo’s father was a great Spirit Caller of his people, who led the fight against the nefarious fire cult of the Waponi tribe. When he vanished, young Mormo was left in the care of the kindly tribal Chief, Omurtu. As was custom, Mormo was groomed to learn the way of a tribal Shaman and become the new Spirit Caller, but he became obsessed with finding his father – he left Rapa Nui for many years on a quest that was ultimately fruitless. In that time he learned magical secrets from many other Witchdoctors, and the traditions of his people gave way to a love of adventure and by the shiny glitter of Pirate gold. When whispers of a great lost treasure trove reached his ears, Mormo couldn’t help but turn his back on his birthright to seek his fame and fortune in the skyways of the Spiral.
