The arcade the group enters is lined with columns, and a few dilapidated (and empty) rooms to explore on either side. But it does not take a discerning eye to see that this place was elegant once. The architecture appears simple at a glance until one wipes away the grime and sees the quality of the stone.

One column is broken from the base, and a wall of dirt caved in its wake. This part of the passage is piled almost ceiling high with debris. And while the space at the top may be sufficient for the smaller party members to crawl through, it will need a bit of clearing to admit an adult. Fortunately, it yields to careful hands. With some digging, the party will be able to clear a path for everyone. On the other side is only dirt and pebbles to slide down and continue onward.

(Though, it will make an awful lot of noise. Hope you weren't going for stealth!)
