The Central Core is the main HUB-world of MainFrame. It appears in the form of a large room constructed from various computer parts, most notably motherboards. The area also functions as a bridge between the other worlds, housing nine different portals which can be activated each time a world is cleared.
This is the first location Zelix finds himself in upon entering the game, and it is here that he meets Beth. She joins the party after a brief conversation, and leads the boy into the first world: Hillside Meadow.
