Little is known of Betancore's life before he was recruited by the Inquisition, only that he was a fine pilot.

Midas was killed by Fayde Thuring in unknown circumstances.

Betancore was a dark skinned man, with his hands covered in inset Glavian circuitry. This circuitry allowed him to directly interface with ship functions, enabling him to react faster and draw far more performance from his craft than a normal pilot would. He preferred not to blend in with the crowd on occasion, proudly wearing the red-piped black suit of a Glavian pilot.

Midas was fluent in a form of coded language developed by Eisenhorn and his retinue named Glossia. The basic format was created by Eisenhorn when he was 32 years of age, but it grew organically with use over the years, with several of his employees contributing to its form.
