Make a concise location description of a spooky lake in the wilderness with linden trees and a mysterious building.
assistant
A grove of linden trees grows almost to the banks of a large, pristine lake, its waters a shade of blue usually reserved for only the most beautiful of sapphires. Here and there, drifts of fog rise from the mirror-smooth surface like wraiths twirling in a slow-motion dance. Due north, on the lake's distant shore, stands an unusual building. Three towers flank the domed structure, and drifting fog girds its striking configuration like a robe of mystery.
