Dean's temple is pretty much the Men of Letters Bunker with a small bar/rec room inside.

The Temple's entrance is rather well hidden, tucked away in what appear to be abandoned ruins; just a bit below ground level, looking like a relic from an old fallout shelter. The bulk of the temple is in fact underground but the ruins serve as a facade to hide the sections that are above ground like a ventilation system and the like.
There are two levels to the temple. The first - directly at the door leads to multiple room. These include but are not limited to basic bedrooms/living quarters, showers and things of that nature. The ground level down the metal staircase leads out to the main room which contains a massive meeting table. Off to the right a kitchen. To the left a library - it's large but there are several shelves noticeably empty. There are multiple rooms branching off of the ground floor, many of which locked and sealed tight - including a dungeon, an indoor shooting range, a lab, an infirmary and storage - there's even noticeably empty car garage. The living room branches off into something like a den, there's a pool table, poker table, and the basics of a bar tucked away inside.
The furnishings inside are old from the late 50's or in some instances the 30's and kept simple and tasteful. There are symbols, sigils, and wards carved or directly in the design of the floor tiling, wooden bookcases, etc, etc.
