Frobin was a soldier serving under General Shele in the Hynerian Navy. He was part of Shele's force that joined up with Peacekeeper Commandant Aeryn Sun in the Falaman System, a refuge from the Kkore forces during the War for the Uncharted Territories. Frobin, however, was unhappy with his general's choice to follow the orders of Commandant Sun, believing she was too tyrannical in her command and that many of the gathered force should have the freedom to fight the Kkore however they chose.
