Biography

Before The Fall, Callus worked at a major GRE complex in the United Stats of America in Washington DC. He was one of the doctors involved with creating THV, being the primary operation manager. However, once THV had broken out into the world, Sullivan was given a new task of creating a cure for it, he also requested Marcus Ryan as his lead security officer. After sometime before Callus and his team could finish the cure, a large group of Infected reached his complex and demolished Marcus' defenses. But, before they Callus, Marcus and remaining GRE personnel could be killed, they managed to escape in a GRE Chopper. Sullivan made a false report of his and the other personnel deaths to cover up his new operations at the newly re-instituted GRE National Laboratory.
