The star system where the Enterprise-D met DaiMon Bok's Ferengi marauder in 2364 and Picard was handed back his lost former command, the USS Stargazer.
The Xendi Sabu system is a star system featured in the first-season Next Generation episode The Battle.
In 2364 the Enterprise-D waits there for days at the request of a Ferengi ship commanded by DaiMon Bok. When the Ferengi finally come aboard, Bok announces a gift for Picard: the derelict USS Stargazer, which Picard had abandoned nine years earlier in the Maxia Zeta system after destroying an unidentified attacker. That attacker was a Ferengi vessel commanded by Bok's son.
The gift is a trap. Bok has hidden a thought-maker device aboard the old ship, and it torments Picard with headaches and false memories until he beams over and prepares to repeat his famous manoeuvre against the Enterprise. Riker and Data stop him, and Bok's own officers remove him from command.
