Vault of the Echoing Lattice

The party pushed through a fractured stone door and found a small, forgotten cache in a side chamber of the dungeon: an iron-bound alcove ringed with faded ward glyphs and dripping mineral deposits. The room looks like it once served as a quartermaster nook — a few weapons and trinkets left behind in haste, a water-stained codex tucked into a shelf, and niches holding jars of alchemical resins and a handful of gems. No guardians remain; the ward glyphs are spent, and the trophies are ripe for reclaiming. This haul is what a level-5 party might reasonably discover while clearing lower vaults of an older keep: a mix of coin, a minor magic weapon, consumables, useful crafting reagents, and a few sellable gemstones and lore items.
