He explains that after performing its ritual, the Silver Key took Carter to the Outer Extension, a realm transcending spacetime, by transporting him through a cosmic structure known as the First Gate. There, Carter met the Ancient Ones, a group of mystic beings led by 'Umr at-Tawil, a dangerous being warned of in the Necronomicon, saying those who deal with it never return. 'Umr at-Tawil offers Carter a chance to plunge deeper into the cosmos; after Carter accepts, the Ancient Ones manifest and open a structure known as the Ultimate Gate, which takes him to a truly infinite void...
