Betrassus was a planet located in Sector 1417. It was ruled by a monarchy. It was home to at least two members of the Green Lantern Corps. The first, the king's son Ragnar, was inducted only briefly as a trap to lure him to Oa to be arrested after being responsible for several murders, including that of his own brother and the Green Lantern Myrrt. The second, Ragnar's sister Iolande, was chosen by the sector's other Lantern, Soranik Natu, to succeed Myrrt.
