The structure built at the very tip of the Cosmo Cavern Tower. Bugenhagen once lived here, he also once ran the Observitory; a truly magnificent invention of his in which you can actually see and feel the universe... in 3D even. There are more nifty things that can be done, but only the likes of Bugenhagen and Nanaki know of them. The Observitory is now the home of nanki, Red XIII.
