This rounded chamber looks to be the inner sanctum of some religious
cult.  There is a large oaken table used for meetings and a large religious
icon surriounded by a pentagram on the domed ceiling.  Chairs are scattered
left and right in a disarray.  The pentagram has diametrically opposing
magical sigils on every point.
