Originally one of the first “Futurist technology” companies, The X-Arc Corporation dealt in cutting-edge science across multiple disciplines, with many of their early successes created by Stephen Armandan. After his departure to start Armada, Inc, they were most well known for their production of Anti-gen, a chemical capable of suppressing the mutant gene.
In the Early 2000s, The Defense revealed their wide-spread, illegal experimentation on mutants. After the Corporation was following a government inquest, a number of their former employees went rogue, evading arrest to continue their immoral experiments, leading to the X-Arc cells that we encounter today.
In recent years, The Defense has discovered evidence of an individual known as The Director coordinating some of these cells.
