Aetherion Bastion is not Hell. Hell is the Infernum, and the Infernum is a containment for corruption and for the demonkind that grew from it. Aetherion is something stranger and, in certain rooms of the higher orders, something more feared. It is a divine prison. Its function is to keep alive what cannot be released and cannot, by the agreement of the Gods themselves, be destroyed.
It does not appear on any mortal map. It has no shoreline, no horizon, no weather. It is guarded by Divine Angels — those who serve the Gods directly and are not bound to any one world — and the guarding is constant, and the rosters of the guarding are not written down in any place a copy could be made.
What is kept inside Aetherion is not, in the celestial accounts, named openly. The accounts speak only of doors. There are doors inside the Bastion that even the Gods have agreed never to open again. There are corridors that the Divine Angels walk past with their eyes deliberately on the floor. There are silences within it that have been silences since the architecture of creation was first set, and that the higher orders, when pressed, will say only that they intend to keep that way.
The chronicle does not yet know whether anything Drexel is doing has any reach toward those doors. The chronicle does not yet wish to.
