Kalishik, the wooded planet in the Kalishik system, was positioned in the Back Reach of the Gordian Reach sector. This forested world fell within the Trans-Hydian part of the Outer Rim Territories. The Ardan Cross hyperlane provided a connection between it, the Arda system, and the Feena systems. The sentient T'sarki species originated on Kalishik, their homeworld, which also possessed a small industrial foundation.
Daniel Wallace and Jason Fry introduced Kalishik in The Essential Atlas, a reference book from 2009; it was located in grid square Q-6.
