Backstory:
The Wraith is a undead that came back to life 127 years ago, the means are necromancy. The Wraith was a shadow mage, and decided to live out their afterlife helping the world. The Wraith killed people who they thought would cause bad things to happen. At 106 years into their afterlife, The Wraith killed a rouge working for 4 families researching eternal life, and while doing so he accidentally injured a child named Cassius Kalish and healed his physical wounds, then left the scene. A little later into that year, The Wraith killed the 4 family's parents because they were on the verge of figuring out eternal life, then using that knowledge for only themselves. The Wraith learned of 4 children of the people they killed and felt horrible. The Wraith trained the 4 children, until they were 20. The order they became 20 was Manta first, then Scorpion, then Cardinal, then Hound. The Wraith was never seen by any of them again after they left, and they don't know where they trained. The Wraith's current whereabouts are unknown by any, and they haven't made any more moves.
