Uh, actually that "island/house" in the barrier is the top of Alexander's corroded head covered in sand. Alexander's body is just dormant and submerged prior to the HW main story completion. The Goblins just reactivated him. The Primal's mechanical body was always there and the summoning kinda reformated it. You can even see this happen in cutscene #14 of the level 60 "Heavensward" Quest in the Unending Journey.
