Vindicta

A victim of John Hathorne during the Salem Witch Trials, Vindicta got a second chance of life when her spirit was brought back to the mortal plane during the first Maelstrom (the event that introduced the supernatural to the public at large). Waging a one ghost war against "The Friends of Humanity", a neo inquisition formed by Hathorne's descendants; Vindicta looks to keep the supernatural safe from Hathorne's ilk, and she isn't afraid to stack as many bodies as needed to do it.
