Thuldanin

The scrap heap of the planes, Thuldanin is the second layer of Acheron, and home to creations both worthless and wondrous from across reality. The cubes of Thuldanin are hollow, and pockmarked with pits and tunnels, the deepest of which lead into the interior of these cubes: vast realms of nothing but old machines and constructs that have somehow made their way to this layer, only to have long since been petrified by its magics.

This petrification can be a hassle for those intending to stay here for long periods of time, as it effects all items taken into this layer. In some locations, it can be even more hazardous, affecting people as well. Natives of Acheron, though, are immune to this effect in any location. However, given that this still affects even a native's possessions, this layer is almost entirely uninhabited; still more populated than Tintibulus and Ocanthus, but few true residents of Thuldanin can be found outside the duergar of Hammergrim, where Laduguer protects even his people's possessions from the encroachment of Thuldanin.

The preservative nature of Thuldanin means that any item left on this plane has a cumulative 1% chance per day for every day beyond 30 of turning to the same iron-like stone that composes the cubes of Acheron. This can only be reversed by powerful magic on the order of a wish or miracle spell.
