Richard Rider (Earth-616), Marvel Database

Richard Rider was born in Hempstead, New York. As a teenager, he was chosen at random by the alien Rhomann Dey, last surviving Centurion of the planet Xandar's elite Nova Corps, to inherit his power and succeed him in the rank of Nova Prime following the destruction of his world by the intergalactic pirate Zorr. Having been mortally wounded in the battle that tore Xandar apart, Dey succeeded in tracking Zorr to Earth, but he was unable to exact vengeance himself due to the extent of his injuries

I expect in the sequel we get some flashbacks about this galactic war and Richard Rider : r/PlayGOTG
