Vault of the Twilight Regent

Hidden beneath a forgotten observatory is a vast chamber once tended by a reclusive archmage who tracked ley currents and collected rare artifacts. The party opens the ancient vault and finds a curated magical treasury. Shelves hold high arcana gathered from ages of bargains and bargains unpaid. A central dais cradles legendary items intended to anchor huge rituals, while cabinets and locked glass cases contain practical marvels for long campaigns. The group may take the most powerful pieces at risk of attracting attention from other planar hunters, or pocket coin and gemstones to fund future endeavors. Two items appear to be unique experimental constructs from the Regent's work and bear small stabilizing wards, suggesting they were never sold to the general market. The rest are classical treasures, suitable for a level 20 party preparing to reshape the world or defend it from cosmic threats.
