They were the most elite, totally dark, special operations team. On. The. Planet. Officially, Wraith team did not exist in any known database. Unofficially, the team of badass SEALs were the ghosts who handled the missions that official spec op teams couldn't touch, and didn't want to. Until they were betrayed by the covert CIA unit controlling them.
When the enemy changed the rules of engagement and went after their women, the newly decommissioned SEAL team perceived it as a declaration of war. In retaliation, they formed their own private security agency. INVICTUS Security had one mission objective. To destroy the Illuminati, the secret cabal behind the CIA unit.
Against all odds. At any cost.
Failure was not an option.
