This mod will allow you to get magical power by selling the soul of another character to the Old Gods. There will also be 3 new spells and various gifts that you will receive from the Old Gods, but if you anger them, you will become a vampire.
This mod for The Sims 4 will make a sim keep a copy of a book after the book is published. Self-written books in the sim's inventory which have already been submitted to a publisher or the literary digest cannot be republished and will be grayed out.
