Star Wars: Void of Mysteries
The vornskr, native to the planet Myrkr, were a wild, vicious canine species that had the unusual ability to sense the Force. This ability evolved to help them hunt ysalamiri, but a side effect caused them to think that Force-sensitives were their favorite prey, including Jedi in their appetite.
To counteract this hunting method, the ysalamiri developed the ability to project a “Force bubble,” inside which no Force abilities could be used.
Vornskrs were primarily nocturnal hunters, and used their whip-like, mildly venomous tails to stun prey before finishing it off with their teeth. They were normally sedate during the day, but hunger or other factors would drive them to hunt during daylight hours.
