The Haul is a massive, roughly spherical object towed behind the Drifter's ship, the Derelict. It contains a pocket of Unknown Space as part of the Nine Realms much similar to The Third Spire.[1] [2], accessible via an opening in the side facing the Derelict. The location within this pocket serves as the playing field for the Reckoning, a challenge co-orchestrated by the Emissary and the Nine.
According to an analysis conducted by the Praxic Warlock Aunor Mahal, the Haul is an "engine of pure potential," seemingly capable of manifesting any entity imaginable by its user. The Drifter has taken advantage of this ability by hooking up his banks to the Haul, allowing him to create "counterfeit" Taken Primevals for his games of Gambit Prime.
