Since he is in a different "shard" of the Gem of Immortality who retrieved the Codex of Ultimate Wisdom from the Gargoyles?
Ah. Actually, the Avatar exists in the original Britannia, not in another shard. The shards each contain a copy of Britannia, but the shards themselves (at least some) still lay in what we could call Britannia Prime. In our worlds, the Codex has never been discovered by the humans, and never recovered from the Abyss. This will form an integral part of the Stygian Abyss lore, as we explore what relationship the Gargoyles have maintained with this incredible artifact.
