Larger than fully-grown humans, krykna were giant, spider-like creatures native to the remote world of Atollon. Predominantly white, they had six powerful legs, eyes around their head, and a blaster-resistant hide, making them fierce hunters. They often take their prey into an underground hive, where they cocoon their victims. Krykna attacked the rebels looking to establish a base on Atollon but the creatures were repelled by sensor markers.
