Decisions of Life and Death: Tech Book

This is not an actual story, but a kind of Tech Book for my story "Decisions of Life and Death" where I'm going to gather the in-depth details of certain spells from now on, to keep the dry details from disrupting the flow of the main story. At the moment that means the inner workings of Stellar Spirit Magic and Urano Metria. Rated M because the actual story is M too.
