The reptilian head of the Selay delegation carried aboard the Enterprise-D to the conference at Parliament in Lonely Among Us, bitter enemy of the Antican party.
Ssestar is the chief delegate of the Selay, a reptilian species of the Beta Renner system who are applying to join the Federation. He appears in the first-season episode Lonely Among Us.
The Selay and their neighbours the Anticans loathe one another, and the Enterprise has to ferry both delegations to the neutral world Parliament. Ssestar complains that his party has been quartered too close to the Anticans, whose smell he says he can detect, and his people are later caught stalking the corridors with snares.
Riker and Yar spend much of the voyage keeping the two sides apart. By the end, one of the Selay delegates has gone missing and the Anticans' cook is asking about a meal.
