Omin Volkas is an Imperial Combine citizen, and a resident of the planet Guathelia. He is in his early twenties, but his occupation is not known. He is the nephew of Bullseye Company's First Platoon CO, Lieutenant Pavin Volkas, and the partner of Halfre Blesson.
On 13th March 3745 ELC, in the wake of a hostile incursion, Omin fled his home town along with Halfre, MAGA soldier Junn Delanka, and a child named Caela. During their escape from the town Omin was instrumental in defeating a group of Rasas, killing most of them with a grenade and luring another towards Delanka's field of fire. After this encounter the group made for a MAGA training facility at Camp Camillion, where they hoped to find sanctuary (→SFTD).
During their stay at Camp Camillion Omin began to exhibit strange behaviour, to the point where he almost stepped off the edge of a battlement wall. This compelled Junn Delanka to restrain Omin prior to leaving the camp temporarily, as Halfre was not certain she could control him if left on her own. On his return, Delanka found that Omin was muttering strange phrases (→LOTD).
Halfre has stated that Omin suffers with headaches which can be triggered by "the slightest thing" (→LOTD).
Omin was rescued from the surface of Guathelia — along with Delanka, Halfre, and Caela — by a combined MAGA and Tanker force sent to the planet as part of Operation Keystone. They were lifted to the ICS Disputer, then transferred to the research vessel Vavilov, accompanied by Pavin Volkas (→TRD).
Omin is still aboard the IRV Vavilov, recovering under the watchful eye of his uncle. His previous infections by the organism known as the Blight appear to have conferred some degree of immunity against the Rasa virus (→FSS).
