THULDANIN

Similar to Avalas, Acheron’s second layer is also filled with titanic metal cubes. On Thuldanin, however, these cubes are pitted, broken, and hollowed out. Each one contains scrap metal and stone from across the multiverse piled in great heaps with no apparent thought or design. Shattered ships, broken flying devices, siege machines, war chariots, and so much more lay hidden in the scrapyards of Thuldanin.

The amount of usable scrap draws the attention of many armies from Avalas and across the planes, but Thuldanin doesn’t just hold its metal fragments. Some natural property of the layer eventually turns all objects to stone, rendering their magic and pieces inert for all time. The process is slow, usually taking thirty days or more for inanimate objects, but living creatures that visit the layer can turn to stone in as little as half a day.

The only known native inhabitants of Thuldanin are the duergar dwarves of Hammergrim. There, the protections from their dark god keep the petrification power of the layer at bay, and the dwarves busy themselves with reconstructing the junk of the multiverse for their own purposes
