The Silent Sovereign's Hidden Cache

Hidden behind a sequence of pressure-plated tiles in the heart of the dungeon, the adventurers discover a small, dust-caked alcove. Within it rests a weathered stone chest, its lid carved with the faded imagery of a king looking over a subterranean valley. The air here smells of stale incense and old copper, suggesting that these items were placed here as a safeguard during a long-forgotten siege.
