Corbinites (Race)

The Corbinites were an alien race who lived on the planet Corbin, in aerial cities.  When he was freed, Surtur sent his Fire Demons to attack them, and ultimately caused their star system to go nova.  The Corbinites created Beta ray Bill as their champion, and loaded the sleeper ship Scuttlebutt with the last members of their race to escape the nova, but they were pursued by Fire Demons and the possessed Enchantress until defeated by Beta Ray Bill, Thor and Sif.

It is unknown why Surtur attacked their race.
