Built into the northeast corner of the cavern, only the south and west faces of the Tower are visible, stretching to the ceiling a hundred feet above. The stone walls are perfectly smooth with no ornamentation. Slightly over halfway up, three rows of half a dozen glowing lights mark what appear to be narrow windows.
Just south of the Tower a stretch of smooth stone interrupts the natural formation of the cavern’s eastern wall. The massive Dragon Door is embedded in the rock below the structure’s center. Three rows of a dozen evenly-spaced slits line up with the glowing windows of the tower. Multiple of the openings glow with the same light as the Tower and occasionally shadows can be seen moving beyond the wall.
