Devidia II was the inhabited second planet in the Devidia system. This system was located in the Marrab sector. Devidia II was the only known location of the cellular fossil LB10445, which was discovered on mid-24th century Earth but apparently originated from the late 19th century. It was later discovered that the planet was inhabited by an intelligent species, the Devidians.
Captain Jean-Luc Picard referred to this mission a few months later, when he remembered the use of a subspace force field on Devidia II. The same technology was needed for the mission to beam on board the Enterprise-D, which was trapped in a temporal fragment. (TNG: "Timescape")
