The High Priest has lived for so long, and the world's will is reluctant to accept him. It's clearly not because of disdain, but to let him continually settle, and then become greater.
When ordinary Naru people die, short-sighted ones can see certain events happening in five or ten years, while long-sighted ones can see twenty or thirty years ahead.
The High Priest's foresight before dying, however, spans through an unknown number of years, an incomprehensibly vast time for even the High Priest.
In the foresight, he saw a giant and evil thing awaken, stirring up towering sea waves, causing all lands to sink.
It was a future filled with despair and destruction.
In the desperate future, the High Priest saw a glimmer of light and instructed his successor to record the prophecy on a stone slab and seal it away.
The instruction was to only unseal the chamber and retrieve the slab before the true arrival of the apocalypse.
