The party enters the World of the Dead, a virtual world inside an ancient supercomputer, overseen by OSIRIS.
Therein, they discover the fate of the people of ancient Imaskar; they live in a world of imagination, a perpetual dreamstate they think is reality. But their afterlive will not last forever; even if it is never unearthed, the supercomputer will someday run out of power, and their memory will be erased.
After a discussion with OSIRIS, they agree to transport the Disks of Eternity, the hard drive of the supercomputer, and thus the living memory and eternal "souls" of the Imaskari people, back to the Ship of the Gods, where it will not only be allowed to move on to eternity by reconnecting with the Imaskari universal network, but will also re-enable the ship and all of its powers.
