The upper level of the Lady's Light culminates in a large circular chamber dominated by an elaborate rune-like floor design and a central spiral stair. The surrounding architecture is cleaner and more monumental than the lower caves, giving the space the feel of a destination rather than another transitional floor.

For a GM, the geometry does most of the encounter framing. The central stair provides an obvious objective and vertical connection, the broad patterned floor gives a major confrontation room to breathe and the circular boundary keeps every combatant relatively close to the action. In Curse of the Lady's Light, this level functions as the upper culmination of the monument's internal progression. It can also serve as a wizard's tower summit, arcane observatory or ceremonial chamber in another campaign.
