Revenants

A revenant forms from the soul of a mortal who met a cruel and undeserving fate, provided a large enough source of necromantic or magical energy is nearby. 
Revenant souls claw their way back into the world to seek revenge against those who wronged them. They reclaim their mortal bodies at first, but if they are vanquished on their quest for vengeance, they will inhabit the bodies of others who are recently deceased. 
Their strength is often far greater than what they commanded in life, they know the direction and distance to their quarry at all times, and the hateful memories of the injustices they suffered can rend their enemies paralysed in judgement at a mere glance from the revenant. 
However, for all their great strength, revenants have one mighty weakness. They must find their revenge within a year and a day, or they'll fade away to naught. A revenant that realises its too weak to slay its quarry will often seek out powerful allies - mutual enemies to their quarry - who they can lead to the object of their revenge.
