Observatory of Mirag
Though obvious seams are visible across the structure, it is in fact a monolith; the apperant seams are intersections of the astral plane in different places, hence the straight lines. Under the object, there is a series of five concentric glimmir discs, called lenses; by changing the order in which the lenses are arranged, one can change the focus and object being observed. The manipulation and adjustment of the lenses is done via the usage of the primacognita (see below) and is literally impossible to explain. Only by studying the true nature of existance one can even attempt to utilize the primacognita for more than simple scrying.
