He was assigned to Gateway Station during the period of the Reckoning and was ordered to escort Jake Sisko back to his quarters during Dukat's rampage on the promenade. Instead took he took Jake to an airlock to allow him to escape the station due to a promise he made to Kira about looking out for Jake's safety. Jake refused to leave and he opted to follow and help Jake with trying to find Kira Nerys.
Lenaris and Jake managed to rescue Kai Winn Adami from the promenade while Dukat was distracted by Weyoun. He followed her to the station's Ops centre before evacuating with the rest of the stations population. He was taken to the Celestial Temple by the Prophets following the conclusion of the Reckoning.
- While not explicitly stated, it's assumed Lenaris would have evacuated on the convoy that left the station. He also would have been one of the Bajorans that disappeared when the orbs passed by the convoy.
