Buildings of Mist

...I wonder why they all look the same.

— Niarelle

All the buildings in the village named Mist on the island of Noble look almost the same. The village contains 1072 buildings. 987 of the buildings are residential, while 85 of the buildings are for storage and other uses.
The residential buildings are all made out of wood, have two floors and the walls are not painted. The window panes are painted black. All the roofs are flat and made out of wood and clay. All houses have vegetable gardens growing on their roofs.
The feature that most visitors find creepy with the buildings is that all doors are painted black and have a weird symbol painted on all the doors. In the neighboring village, the old ruined village, the doors that are still intact looked like normal doors.
