A lone Class M planet orbiting a T-Tauri type star in a pocket of the Ngame Nebula, a rare combination. It has a nickel-iron core and a nitrogen/oxygen atmosphere. Scanning as lifeless, it had actually been terraformed by xenophobic energy beings who stunned the U.S.S. Enterprise NCC-1701-D and, short of its destruction, had short-term memories of the visit erased.
