[Apollo is briefly silent, wondering just how to explain what he's experienced. He knows all too well that it would sound crazy to anyone who hadn't been there, or wasn't even familiar with the concept.]

... There's a technique called spirit channeling. It's a rare talent, but I've met a few people now that can do it. My boss' old court assistant, for one.

They perform a ritual that calls upon the dead, and it works. The spirit medium becomes possessed by the ghost they summoned, and what's more, their body changes to look nearly exactly like the dead person. For all intents and purposes, they can bring the dead back to life... for a while.
