Haunted Vault is a stone crypt set within the cemetery of Drezen, with tombs and narrow interior spaces turning the burial site into a compact underground threat. Heavy masonry, enclosed chambers and dark corners keep sight lines short, while the arrangement of graves and passages creates obvious places for undead or other defenders to appear close to the party.

For Wrath of the Righteous: Sword of Valor, the vault can be treated as a security problem after larger fighting in the city: a place that must be checked and cleared before the surrounding cemetery is truly safe. A GM can use doors, tombs and cramped transitions to make each new chamber uncertain, and the additional mapped sections allow the crypt to feel deeper than a single room. Outside the Adventure Path, the map works as a haunted family vault, military mausoleum or cemetery dungeon where the confined architecture keeps even a small number of enemies dangerous.
