Monster Name: Greater Earth Blight
These amorphous clouds rapidly swirl with violent energy. Within the maelstrom, dozens of humanoid shapes materialize and vanish within an instant. Faces scream in silent agony while hands desperately clutch and claw at the air around the mass.
Bîaŵacs (spirit winds), as these storms are known, often create blights. If souls are ripped free of bodies and caught in the center of the storm, they may become stuck together and bonded with any other elemental substances in the maelstrom. They are pure chaos and confusion, and destroying them is considered a mercy to the souls trapped within.
Experimenting with blight creation is yet another questionable activity that has earned animancers a bad reputation in many circles. Some see it as dangerous and inhumane, others as a means to an end. The creation of blights is an accusation many fearful kith level at animancers.
