Zelkin Parasite

A piece of Zelkin that was separated from his body. Unlike Zelkin, these creatures are incapable of speech. They can latch onto an animal, an object, a robot, a plant, or a person, starting a painful transformation process that takes 1-3 hours. They are capable of levitation until they attach to a host.

Edit: We've run tests, it seems that dogs and cats are immune to the infection. People with a strong enough willpower or spiritual power are also immune, and have a chance to bond with it.
