The inhabitant, Abin Sur, explained (using his power ring to translate) that he was a member of the Green Lantern Corps. Mortally wounded, he searched Earth for the most worthy successor to pass the ring on. Hal, chosen because of his fearlessness and honesty, was given the power ring and its battery, becoming the Green Lantern for Space Sector 2814.
SINESTRO - Hal Jordan's "mentor"
A native of the planet Korugar in space sector 1417 (as the Guardians designate space), Thaal Sinestro was originally the greatest Green Lantern that the Corps ever had.
