Vault of the Sunken Ledger

Deep within a damp level of the dungeon the party finds a sealed ledger chest wedged beneath a collapsed stair. The chest yields practical supplies a dungeon explorer would stash for long campaigns. The Bag of Holding and magical items appear to have been hidden by a cautious courier who intended to return but never did. The potions and spell scroll are well sealed and ready for use, while the gemstones and repair plates are tradeable at nearby markets or useful for local artisans. The rune-forged limestone is an unusual find that hints at deeper rune-work in the dungeon and offers an opportunity for crafting or a side quest to discover its purpose.
