2. Prologue: Beyond Endless
A few years after the events of the series finale, Warehouse 13 met William Damarcus. William is a man out of time, born six hundred years ago. Throughout history, he had himself been made into an artefact, a human artefact, due to the horrors he had seen over the centuries. His powers include teleportation, healing and the wiping of memories. Despite William's dark, haunted mind and psychopathic tendencies, he fell madly in love with Claudia, and she felt the same way. They eventually married, but not for some years.
William stole the DeLorean from the movie aisle of Warehouse 13 (he was tempted to take the T.A.R.D.I.S, but didn't fancy space travel). Using this, he assisted Warehouse 13 throughout the years, travelling through time, until he disappeared.
He came back forty years later, finding all the agents of Warehouse 13 dead and replaced, with Claudia the new Caretaker. She needed assistance shutting down a reactivated Warehouse 8 before the existence of two Warehouses at one time flooded her mind. However, he refused to work with the new agents, and went to revive Arthur Nielsen, Pete Lattimer, Myka Bering and Steve Jinks: the old agents of Warehouse 13.
During the activation of Warehouse 8, Warehouse 13 threatened to move to a new host country, thus becoming Warehouse 14. William instead moved Warehouse 8 to England, renaming it Warehouse 13b and making himself Caretaker, thus allowing two Warehouses to exist at once. Warehouse 13 and Warehouse 13b worked together for some years, the old, revived Warehouse 13 agents acting as the agents of Warehouse 13b. Everything was perfect.
