Miles, from Martian Dreams
The Avatar found Miles guarding Argyre in Martian Dreams. The thug said that Rasputin (Raxachk in the monk's body) had told him that everyone will just try to take advantage of him and manipulate him into doing things. Thus he'd only let Rasputin manipulate him. Miles also gloated that even though the Avatar managed to get in, they'd never be able to stop Rasputin's secret plan, revealing that Raxachk had the rocket fuel.
Before Raxachk later fled Rasputin's body, he murdered his thugs, including Miles.
