Akorem disappeared in the Bajoran year 9174 (2172 on the Gregorian calendar), while aboard a lightship that left Bajor. It was damaged by an ion storm and drifted into the Denorios Belt, where it entered the Bajoran wormhole. Akorem encountered the Prophets, who healed his injuries.

Akorem left the wormhole in 2372, although just moments had passed as he experienced them. Since he had discovered the wormhole before Benjamin Sisko, the Emissary of the Prophets, Akorem was declared the Emissary. Sisko, always uncomfortable with the Bajoran's views of him, quietly stepped aside and let Akorem take the title.
Akorem pushed for the return to the D'jarra caste system, which had been abandoned during the Occupation. This sent shockwaves through the entirety of Bajoran society and threatened Bajor's entry into the United Federation of Planets, whose Charter disbarred planets who practiced caste discrimination. Sisko later took Akorem into the wormhole to speak to the Prophets, who confirmed Sisko as their true Emissary, having little understanding of linear time. Akorem was returned to his own time, where he finished The Call of the Prophets. (DS9 episode: "Accession")
