UnderDim

Underdimension. A place where reality seems to have been cracked or broken. An odd pocket dimension. A place where its easy to hide, difficult to find your way around. Unusually, no neighborhood identity. House of customs has a heavily militarized base right outside to help control area. Noises sometimes come out of it, and can be heard from a mile away. Otherworldly singing, sounds of animals fighting, water dripping. The underdim is also pretty recent and just appeared one day. It replaced a previous neighborhood that sometimes you can see echoes of in a haunting, odd way. There's a department of scientists that researches and tries to prevent cracks from spreading, funded by the royal family. Old neighborhood was named Chamberside.
