EarthDawn - The Age of Legends
The Horror Ristul is known as the embodiment of corruption itself. It’s name means “Corruption Ever Acting”, and it is often worshiped like a Passion by both Horrors and severely corrupted Name-givers.
Being the very essence of corruption, Ristul has no physical or magical form that can be encountered or attacked. It’s “presence” is the corruption that extends throughout astral space, spread by Horrors and tainted Name-givers wherever they travel.
