Resting his back against a wall, Cain skimmed through another book.
Since he was already here, he decided to stay a bit and scan through Steve's collection for a while.
His mind was able to process details at high speeds, so even if the book was voluminous, he could go through it quickly and still remember the contents.
In Steve's small library, most of the books were related to alchemy, toxicology and a bit of mysticism.
Although he didn't know much about mystiscm, Cain could infere from what he had learned so far, that it involved borrowing power from strange entities or beings to activate spells, possibly through rituals and special incantations.
A rather common example of mystiscm was Divine mystiscm, something he had witnessed already with Celestials being able to possess the bodies of their champions.
