To return the Codex to the Vortex, place a convex lens exactly midway between the Codex
and the Flame of Singularity, so that the light from the flame converges on the Codex. Place
a concave lens between the Codex and the Flame of Infinity, so that its light diverges over the
Codex. Then place the eight moonstones within the Vortex Cube. Set it on the ground in front
of the Codex, and use it to return the Codex from whence it came.

Guardians of the Codex - from a tattered parchment

Only those upon sacred quests for wisdom can reach and read the Codex. Within the
Codex is written the one right and true answer to any problem. One has but to reach the Codex,
read it, and interpret its advice properly. The knowledge therein is to be guarded, kept safe
from those who would misuse it for selfish purpose. To ensure this, a select few are to become
its guardians. These chosen few, of virtuous temperament, and wise, shall be known henceforth as
the Knights of Codex.
