Events of Just Cause X: Global eXchangeEdit
While Tom Sheldon was appointed as a head of Covert Ops division and a secret overseer of the Opposition forces in Kyungastan, Keryev was put in command of the USMC elements deployed on Koska island. While "officially" all operations were conducted under command of Brigadier General O'Neill of the US Marine Corps, he only served as a "proxy" figure, leaving strategic and tactical suggestions to Keryev.
While calm and intelligent as he seemed, Commander's true intention was, in fact, revenge against his long-lost brother, colonel J.Keryev who was kidnapped and brought to Russia in his baby years by his uncle, a defector and a rogue agent.
