Ysalamiri

Ysalamiri, one of the indigenous life-forms of the planet Mrykr, have the unique ability to push back the Force. These salamander-like creatures grow to a length of fifty centimeters long. Furry snakes with legs, these creatures live in the branches, making it difficult to remove them from their perches without killing them. A single ysalamiri creates a bubble ten meters in radius in which the Force does not exist. Those who have studied the creatures theorize that ysalamiri push the Force away from themselves as a bubble of air pushes away water. Within this bubble, a Force user cannot call on his or her powers or otherwise manipulate the Force.
