Alternate World Reincarnation

Alternate World Reincarnation is a Rank 7 spell created and perfected by Leylin — one of the most technically demanding and conceptually extraordinary spells in the story. Its core function is to split a fragment of the caster's Truesoul from the main body, transmit it through the Astral Plane, pierce the Crystal Wall of a foreign world, and reincarnate it as a genuine native of that world. The result is a clone that is, in every meaningful sense that the target world can detect, indistinguishable from a being born there — invisible to divine scrutiny, synchronized with the world's origin force, and free to develop along the world's native pathways without restriction.
