Buildings have a spirit, invested in them by love, belief and use. When buildings burn, flood, or are otherwise demolished those spirits pass to the Shadowfell, where they cluster together, tethered in ramshackle and chaotic configuration. Thus are cities and towns mirrored in the Shadowfell plane. Until the towns or cities themselves die, and all fade away.

Make no mistake, this is still the Shadowfell. The buildings carry their lives forward into their afterlife complete with scars and reflections of the lives they housed. If the home was a house of abuse it will attract the black denizens of the plane. If it burnt to the ground, embers of the fire will slowly course through the wood and furniture. Shops will be reflections of their final days, they will be boarded up, empty shells of the hopeful dreams of the owners.
