A curious arrangement graces the southern wall of the common room. Three arched windows rise high in the stonework, two of them filled with clear, textured glass. The third is crafted from elaborate stained glass, seeming a little out of place next to the others. To the east is a small entryway, and a large marble obelisk stands in the center of the common room.
