This is the "Ythrak Krellinaath" (House of the Exalted), it is kind of "Union Hall" for the pantheon in my home-brew. They meet here to discuss various matters, settle disputes, etc. It is located far in the north on a plateau within a ice-covered mountain range.
The building itself is a rectangular structure made from white marble with a golden dome supported by four marble pillars.
Each throne has the deity's symbol on the cushion, the slightly larger chair at the "top" of the circle is for the pantheon's 'mother'. An Omnipotent being (like AO in the Forgotten Realms), who actually keeps a close eye on her 'children' to make sure they don't get to far out of line.

Thanks to all those who responded with suggestions, critiques, etc.
