Topaline

Topaline is a substance used in life-support systems. Among other places, it was found in abundance on Capella IV.

A survey of Wolf-catalogue stars within a 5-parsec sphere from Sol in the early 22nd century discovered that the fifth planet of Wolf 359 had reserves of both topaline and pergium (Star Trek: Shadowstar Station), which led to the establishment of the Yogyakarta Baru colony.
