Esper

The Esper is a custom class used by those who have died, lived their afterlife, then came back, keeping the powers they gathered in death. They are often charismatic and outgoing- They have tasted death, and it only made them stronger. Why fear anything else? Now returned to the living, they possess strange powers, called Horrors, fueled by the energies of death, called Spite.

Very, VERY rarely creatures with a strong connection to death will manifest similar powers without tasting the afterlife. These are almost exclusively Mortif, but others could exist... In theory.

The Esper class specifically refers to the ones who lived as an Undead entity before returning, however there are also the Fallen and Risen, who lived as Fiends or Celestials before returning to life. Very rarely, other variants will appear somewhere in the world; But these are as rare as the events that might bring them about.
