The Mystery Emporium is a shop located on the third floor of the Chamber of Knowledge. It was first introduced in February 2011. It currently sells Den Portals and stone statues of the Alphas.
The shop is located in a dark brown room that has wood framing lashed together with tan ropes. On the back wall, there is a large, circular window that looks out into a starry night sky. There are two hanging lights on the left side of the shop and interactive candles on the right side, which light when clicked. In the right corner of the shop is an angled desk with a celestial cartography map on it and a model of a solar system hanging above it. During the Solar Eclipse, you could see an eclipse through the window.
