The library had a twisted sense of darkness. With books ranging from lockpicking spells and simple fear focused spells to satanic rituals and blood sacrifices to something higher. She knew she couldn't deal with satanism at this point, or possibly ever, so she started with working on reading up on small curses designed to simply disrupt someone's day. Small things like a stubbed toe, a paper cut, losing possessions and mild threatening situations. She decided that would work as a simple lesson at that spells such as "rediculus" were a great way to mess with an enemy.
