A man named Isaiah Barnes found a superhero base and took an armored suit from the base. The suit was designed to facilitate trans-dimensional travel – heavily armored, teleportation matrix, nano-healing kit and a gate generator. This particular suit was keyed to the pocket universe of Sanctuary and was used by superheroes to store the wreck of a massive alien capital ship, too dangerous to leave on Earth, after it crashed there years ago. The human learned how to use the suit, injected himself with the AR nano package and opened a gate to Sanctuary. He found himself in the wreckage of the the ship. Shortly after exploring it, he encountered Mechanic, an alien salvager. Mechanic made a deal with the human (now calling himself Wayfarer), alien tech for certain goods on Earth – machine tools, medical supplies and laptop batteries.
The gate suit made theft simple. Wayfarer simply found warehouses that contained what he wanted, teleported in, opened a gate to sanctuary, teleported the supplies in, closed the gate and then teleported home. Wayfarer thought this was an equal and mutually beneficial relationship. Mechanic never told him otherwise. As an alien, Mechanic regarded humans rather poorly. The alien felt that if he told Wayfarer the truth, Wayfarer would exploit the situation, perhaps even bring in other humans to steal from Sanctuary. Mechanic even implied that he was part of the alien ‘mafia’ and this was a big criminal enterprise, lying about how it was extremely profitable to sell tech from the ship. Thus, Wayfarer had no idea of the gravity of the situation.
