Above the grand stairwell

This wide marble stairwell is capped by a dome of clear glass. Offices
flank you to the east and west while a suspended walkway traverses the
stronghold from south to north. The walkway passes directly underneath
the massive glass dome. In the center of the glass dome above, thousands
of shards of frosted glass have been mounted to form a four-pointed star
that glows gently in the sky's light. The staircase descends to the floor
below.
