The crushed remains of trade districts of earlier eras create a barely supported network of low-ceilinged chambers; in many places, the roof is only 3 to 5 feet high. In Tyr, explorers can obtain fragments of maps that hint at an old armory in the Crawl stocked with iron weapons, but so far, these maps have not provided enough information for anyone to find the storehouse. Explorers who return from their failed attempts describe the Crawl as a torturous death trap replete with rockfalls and hordes of zombies that seep out of the nearby Road of Crypts.
