The last temple of an ancient order, this sentinel of knowledge sits proudly amongst the desert plains. Constructed of strange bluish stone, dark outside and ever so slightly paler in the interior, I cannot tell how such a thing was crafted. Certainly not by any human hand, though perhaps magic and divinity had something to do with it.
The inner sanctum is dark, though warm braziers are ever present, with it's denizens quietly going about their business. All changes at the midday sun however, as the glaring sunlight beams through the ceiling aperture, light emblazoned on the abstract floor runes. The group who dwell there gather together at this time, offer their arms to the sky and kneel in some communal prayer.
The place is unnerving to say the least, but it is said that these quiet folk hold much knowledge. Perhaps they will part with it for the right payment.
