Atop an imposing mountain - or it would be imposing, if it were not simply one in a considerable mountain range - there sits a mirror-calm lake of icy waters, and in those icy waters swim beautiful silver fish.
Around that lake, towers of white marble - if you look closer, somewhat ruined and then patched up with another, stronger white material - and great courtyards and balconies abound, inhabited by various people in white and blue robes, an awful lot of books, one dodo, and one cat.
Off one end, the lake cascades - quite gently, the outflow is carefully tended - in a beautiful spray, down crystal-studded cliffs.
It is about to have an unexpected visitor.
