Destruction of Halvo BayEdit
Around thirty days after Emergence Day, Perham was part of the effort to defend the city of Halvo Bay from a huge Locust assault. Perham helped defend the Halvo Bay Military Academy from the Locust, but was beaten to death by Ragers in the Monroe Commons. Perham's COG Tag was later recovered by Cdt. Sofia Hendrik of Kilo Squad.
