Vault of the Sunken Cellars

After clearing a collapsed sublevel of the dungeon and prying open a sealed side-chamber, the party finds a modest treasure hoard left by a forgotten guild of tomb-robbers. Broken crates and ancient ropes spill mixed coinage and a trio of cut gems into the dirt. Tucked beneath a stack of crates are two useful potions and a serviceable +1 shortsword whose runes still glow faintly. A sealed spell scroll of knock promises easy entry to locked doors deeper in the complex. Among the mundane goods are locksmithing links and a corroded key that likely opens nearby iron doors, plus a shard of glassy material that hums with echoing magic useful to artificers and enchanters. A small debtor ledger provides potential leverage with local fences or guilds. The haul fits a level 5 party: it rewards exploration, offers immediate consumables and a modest magic weapon, and provides materials and leads that can fuel future adventures or trade.
