Alternate World Reincarnation

Alternate World Reincarnation is a seventh-level spell created and perfected by Leylin, one of the most technically complex and conceptually remarkable magics in history. Its main function is to separate a fragment of the caster's True Soul from their main body, transmit it across 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, in every meaningful sense the target world can detect, is indistinguishable from a being born there: invisible to divine observation, synchronized with the world's origin force, and free to develop through that world's own natural paths without restriction.
