As they're formed purely of anti-life from the Negative Energy Plane, wraiths pervade that unholy realm. Within nations and civilizations ruled by the undead, wraiths have places of power as assassins and spies. They're among the ruling class in Geb, but have greater numbers in Ustalav, where packs of wraiths roam graveyards and misty trails, consuming the populations of entire villages. In other parts of the world, wraiths tend not to wander and limit their activity to smaller environs, typically just the site of their chosen haunting and its immediate surroundings.
