M Cell is currently under reorganization, with the reassignment of several agents and friendlies previously affiliated with other cells. M Cell was organized under the direction of agent Osborne in the interim until a cell leader was assigned, but it was taken over by agent Meredith when Osborne was killed in an apparently mundane automotive accident during the investigation.. The background of M Cell is classified, restricted to A Cell, as is any connection between previous incarnations of M Cell and the legendary agent Matthew.

M Cell is presently assigned to operation SANDMAN in New York City (field report #3270). Operatives include:

Agent Meredith (Cell Leader)
