Twilight looked up. The centre of the ceiling was not rock, but rather a glossy material that looked almost exactly like glass, shining like diamond. The moonlight was striking its multi-faceted surface, condensing into the singular beams that Twilight could see as clear as sunlight. She followed one of the beams as it shone against the wall and watched as the light seemed to coagulate against the shiny black stone. A few drops of silver ran down from the illuminated spot, trickling towards the lake in the middle.
