Line creepers, akin to the conduit worms, were creatures inhabiting the Unknown Regions. These creatures, segmented and thin, possessed the ability to reach lengths comparable to a Chiss. Their method of survival involved gnawing into power and navigation cables, drawing sustenance from electrical energy. A specific gaseous residue marked their presence, and they were unable to survive in environments lacking atmospheric pressure.
As of 22 ABY, the Chiss had been engaged in a protracted, yet unsuccessful, campaign to eradicate them.
