A Betazoid dignitary and old acquaintance of Lwaxana Troi who attends the trade agreements conference in Ménage à Troi and helps the Enterprise when she is abducted.
Reittan Grax is a Betazoid official who appears in the third-season episode Ménage à Troi, set in 2366. He is present at the reception aboard the Enterprise that closes the biennial Trade Agreements Conference at Betazed, which the Ferengi have attended for the first time.
Grax has known Lwaxana Troi for many years and is well aware of her forthright manner, which she turns on DaiMon Tog when the Ferengi makes his interest in her plain.
After Tog beams Lwaxana, Deanna Troi and Riker away from the surface of Betazed, it is Grax who contacts the Enterprise with the news. He assists Picard's crew as they try to establish what has happened and to trace the Ferengi ship Krayton.
