 	description `This station was mothballed sometime in the last sixty thousand years. The docking area has an atmosphere, and a status panel indicates that the station's generators are functional but shut down, with standby mechanisms running on solar power alone.`
-	description `	An immediately obvious difference between this station and the others in Hai space is the presence of a solemn plaque that takes up a sizable portion of the nearest wall. Upon further inspection, it seems to commemorate an engineering malfunction that occurred thousands of years ago, when this station was still inhabited. In a freak accident, an entire habitation section of Darkrest lost power and depressurized, causing the deaths of countless civilians. Thousands of years later, no one knows for sure what caused the incident. Legends, stories, and conspiracy theories have blossomed from the event.`
