Professor Jonas Durns was a scholar and researcher who had specialized in the mythical Dread Buccaneer Hez Kragg.

Durns was bent on finding evidence for Kragg's actual existence. Durns had been able to find sites that may have been used by Kragg and his band. He participated in an expedition that finally allowed him to find evidence of the buccaneer's existence in the form of his ship Kragg's Fury and a holorecording of Kragg himself, as well as the actual remains of the pirate.

Durns was knowledgeable about ancient languages, the study of species, astrogation, and computer programming. Durns was the father of Keya Durns, who would join him on expeditions.
