Space Sector: 2813
Sector Partner: Tomar-Tu
Dalor is a member of the Green Lantern Corps. Dalor was one of the more frequent Green Lanterns seen until Hal Jordan accuses Dalor of being corrupt. The Guardians of the Universe sentence him to a trial. Hal then goes and saves Dalor's planet from a disaster and is then offered jewels. Hal finds out that this wasn't corruption but the culture of his homeworld. Hal goes back to Oa and enters the Anti-Matter Universe to save Dalor.
Dalor met Jordan's successor, John Stewart of Earth and Stewart's trainer, Katma Tui of Korugar during their mission to Zamaron. The two Green Lanterns were investigating the planet in Dalor's sector to discover why some of John's memories had been wiped away through techniques similar to those the Zamarons employed.
As the Green Lantern of Sector 2813, Dalor assisted them in their quest. The trio arrived in time to see the coronation of Carol Ferris as Star Sapphire, the Queen of the Zamarons. Although their memories of this event were also wiped away, a previous mental command to their power rings reestablished the Zamaron erased memories.
During the so-called Crisis on Infinite Earths, Katma Tui had sought out Dalor, only to discover her friend's sector had seemingly been obliterated by anti-matter. Dalor was missing, and presumed dead.
Some years later, he was part of a group of now powerless Green Lanterns rescued from an interstellar slavery ring by Guy Gardner. The former Green Lanterns were taken on a starship belonging to the Darkstars. Dalor returned to service following the Corps reformation. Having been once falsely accused of abusing his power, Dalor is now a recluse, avoiding contact with other Green Lanterns unless it is absolutely necessary. His absence was noticed when his presumed dead sector partner Tomar-Tu returned, and he did not venture to Oa for the celebrations. Tomar-Tu has scanned the sector for him several times, but somehow Dalor stays hidden.
