A Bajoran leader in exile during the Cardassian occupation, well known at Federation diplomatic gatherings but dismissed by Ro Laren as a figurehead with no influence over his own people.
Jas Holza was one of the best-known Bajoran spokesmen during the Cardassian occupation, living off-world and moving easily in Federation diplomatic society. Picard had met him at a symposium and regarded him as the obvious person to approach.
He is discussed in The Next Generation episode Ensign Ro. Ordered to find the militant Orta after an attack on the Solarion IV colony, Picard proposes consulting Holza. Ro Laren replies that Holza is the acceptable face of Bajor, the man respectable people invite to their receptions, and that he has no real power. She steers the captain instead to Keeve Falor in the refugee camps of Valo II, who has no diplomatic polish but does have the trust of his people.
Holza is never seen; he stands in the story for the Federation's comfortable distance from Bajoran suffering.
