"Reedeemer of Light" was a religious figure mentioned by con artists Dala and Mobar. While they were posing as clerics from a hermitic sect, they told a story about orphans at Narva. They claimed to make a pilgrimage each spring to Narva in honor of the Redeemer of Light.
Dala once told Neelix that he resembled the Redeemer of Light. The Talaxian was flattered by the comparison. (VOY: "Live Fast and Prosper")
