The Protectors

Original story, not a fanfic - so I'll try my best
Legacy, Aubrie, and Kadence are the three Wishtresses - and ever since they graduated, they've dedicated their lives to defeating the force of evil that lie within the magic realm.
After a slightly different escaped prisoner comes back to their home, a new friendship starts to emerge. And with evil seeming to take a rest, they have some time... right?
