Incarnation of Sorcery [Stubbing Book 1 in 2 Weeks!]

The Realmbreaker Wars unleashed a thousand, world-ending Calamities. One such Calamity decides to be an academy teacher. Ryland is one of the oldest living apocalypses unleashed by the war. In his case, experimenting with dangerous rift magic shattered his body and scattered its pieces across the cosmos. Pieces that, when left alone, often turn into new Calamities. Armed with a thousand spell glyphs from a thousand worlds, Ryland is ready to stop more of his blood droplets from turning into mad demigods and more neurons from calling down cataclysmic meteor strikes. To do so, he'll need to return to his academy and recover his old research, and maybe teach a few oddball students along the way. But first, he has to pass an entrance trial gone haywire, stop Fate from bullying his pupils, and make sure Calamity-worshipping cults don't ruin his club activities. Surely, a field trip to a different universe can't be that objectionable? Right?
