Where Nod throws away what it cannot use. Vast heaps of scrap metal, spent batteries, broken electronics, plastic packaging, cracked arcane instruments, offal, and unidentifiable refuse from Domains whose waste products do not decompose in ways anyone can predict, piled in mounds that have become permanent topography.
The Skulks have built a parallel economy here from salvage, their warrens threaded through the garbage in tunnels too small and too numerous for larger species to navigate. The smell is constant and specific: rust, rot, and the acrid chemical tang of decaying waste. The Middens attract hungry scavengers of many species, and while lesser middens are scattered across the city, the primary Middens is vast and grows with each visit by the city's Midden Men, an unglamorous and dangerous career that attracts a very particular sort of resident.
