A tower of light-drinking indigo stone crowned by a turning crystal lens, it holds the memory of the elven people. ## Location & Geography The Oraculum anchors the Mnemorium Canton, on the upper northern face of Sumara's caldera — half carved into the cliff and half standing above it, its deep stone halls kept in a perennial dim light. The citadel is a tower of indigo stone that seems to drink the light around it, crowned by a slowly turning crystal lens that throws shifting glyphs across the sky. Like all seven Nexuses, it can lift from its anchor and drift above the city, rising with its sister citadels to dock at the peak of the [[Royal Citadel]] whenever a [[Sumara, The Shining City#The Confluence of the Seven|Confluence]] is called. ## Seat of the Scroll The Oraculum is the seat of the [[Circle of the Scroll]] — Sumara's archivists and lore-keepers — and its Meridian, Archivist Elrohir Gemflower, ancient and absent-minded, with its halls run day to day by the head librarian, Aaroun. The Circle keeps the most extensive historical archives in the known world: centuries of records covering the Material Plane, the [[Chaos Wars]], and the [[Silmara Family|Silmara]] lineage. Most of that knowledge lives in the [[Lectorium]], the great library carved into the cliff below, which stays open to scholars whether or not the Nexus is at its anchor. The Oraculum itself holds the Circle's rarest and most closely guarded records.
