Vault of the Obsidian Archmage

Beneath the crumbling sanctum of an ancient, sand-swallowed city, the party pried open a sealed vault once reserved for a reclusive archmage. The chamber's sigils still hummed with lingering wards; glassy black runes flaked into dust as the party dispelled the last protective glyphs. Inside lay a careful collection of items the archmage preserved for study and power: experimental components, trapped arcane curios, preserved spellbooks, and a few personal treasures meant to endure time. The haul reflects scholarly priorities rather than martial spoils—lots of rare reagents, fragile but valuable relics, and a single well-crafted magical focus appropriate for a lone spellcaster who prized subtlety over brute force.
