Vincent Crowley was an agent of Warehouse 12 who plotted against the relocation of the warehouse to America.
In order to save Warehouse 12 in the midst of a declining era in British history, the Regents were planning to move operations to America. Vincent Crowley was firmly against the relocation and believed England should be allowed to leverage the power of the warehouse.
In an effort to stop the warehouse relocation to America, he first killed Sir James Eddington with Joshua's Trumpet. Next, he activated Sir James Eddington and Helena G. Wells's rocket with Joshua's Trumpet as the power source. He was hoping the launch of the rocket would reverse Britain's fortunes and secure British dominance for the next century.
In the struggle to re-direct the path of the rocket, he was knocked unconscious at the base of the launch area by Helena G. Wells. He was subsequently killed by the blast of Joshua's Trumpet as the rocket launched upward.
