The Quartermaster's Hidden Stash

Deep within the lightless corridors of the dungeon, behind a crumbling section of masonry, the party discovers a heavy chest made of blackened ironwood. The dampness of the stone walls has not managed to penetrate the box, preserving the contents within for decades. This collection appears to be a cache of survival tools and tactical equipment left behind by a high-ranking expeditionary force that never made it back to the surface.
