Vault of the Deep Carapace

Buried within a collapsed wing of an ancient dungeon excavated for arcane experiments, the party uncovers a sealed vault long untouched by looters. No defenders remain — the warding runes have faded and creatures avoided the place for reasons lost to time. Inside are the remnants of the dungeon's last occupants: a curated hoard of high-tier gear, arcane components refined for ritual work, and a handful of curios tied to the site's experiments into boundary-magic. The items here reflect a purposeful collection: tools for high-level spellcraft, a few potent magical implements, and gemstones and metals valued by enchanters and high-tier crafters. The party can divide or appraise the finds, but the vault clearly served a mage-cabal of considerable resources.
