Captain Auson was a Dendarii Mercenary fleet captain. He was originally captain of the Ariel, but when he met up with Miles Vorkosigan, Miles took his ship from him and gave the captaincy to Bel Thorne, Auson's former second-in-command. Miles then gave another, larger and better armed, ship to Auson in return -- the Triumph, which had formerly belonged to Ky Tung.
