A castle made of smoke and ash that squashes the cloud and makes it rain a black and gray that falls when clean snow was meant to come. The floors are ash and the walls are ash and the windows are blackened with smoke.
There was a lady in white she's now an old crone in tattered gray rags who stares through the floor because the window's aren't worth cleaning anymore. Her hair hangs o'er the drawbridge and down cloud and sometimes it shakes and you can see the white like electricity even through the gray.
