In the 2350s, Porta officiated at the shrine in the Singha refugee camp. In 2353, when Kira Nerys entered the shrine distraught, he fetched Prylar Istani Reyla to speak to her. (TLE - Terok Nor novel: Night of the Wolves)
In the 2370s, Porta was one of the monks who tended the Shrine on Deep Space 9's Promenade. In 2372, following Akorem Laan's return from the Bajoran wormhole, Porta supported Akorem's installment as Emissary. He also talked to Benjamin Sisko and agreed with him that as long as Sisko made it clear that he was stepping aside voluntarily, the Bajoran people would support Akorem as Emissary.
Porta later became Akorem's assistant and supported his call for the reintroduction of the D'jarra caste system. Porta later pushed a member of his order off the second level of the Promenade, killing him. Porta did so as the monk had refused to leave the order due to his being a member of the Imutta caste, those who buried the dead. Porta was arrested by Odo and charged, although Akorem planned to ask the magistrate to be lenient. (DS9 episode: "Accession")
