A Bajoran vedek on Deep Space 9 who embraces Akorem Laan's revival of the D'jarra caste system in 2372 and murders a fellow monk who refuses to give up his vocation.
Vedek Porta appears in the fourth-season Deep Space Nine episode Accession. He serves at the station's shrine and is among the first to welcome Akorem Laan, a poet who emerges from the wormhole after two centuries and is accepted as the Emissary in Sisko's place.
Akorem calls for a return to the D'jarras, hereditary castes that fixed every Bajoran's occupation. Porta follows the teaching zealously. When Vedek Imutta, whose family belongs to a caste regarded as unclean, will not resign from the order, Porta pushes him from the upper level of the Promenade.
He admits the killing without remorse. The death convinces Sisko that he must challenge Akorem, and the Prophets confirm Sisko as Emissary.
