The planet where the Soong-type android prototype B-4 was found disassembled by the Enterprise-E. It later turned out that it served as a bait for Capt. Jean-Luc Picard, commander of the Enterprise, put by his previously unknown clone Shinzon of Remus to lure him near the Romulan Neutral Zone, having the Enterprise the vessel nearest to Romulus where Shinzon and his followers had overthrown the Romulan Imperial Senate.
