Le Gardien des Secrets is an Overlord of occult knowledge from the Âge des Démons.

Sul Khatesh, Le Geolier of Secrets is one of the Maîtres Démoniaques who claimed ruled over all of Eberron during the Âge des Démons. She was bound by the Dragons and Couatl after they jointly discovered the Prophétie Draconique, and the Couatl sacrificed themselves to form the Flamme d'Argent.

Sul Khatesh is bound far below the floating towers of Arcanix by the power of the Flamme d'Argent and several tons of stone.

She bears particular animosity towards the Dragons of Argonnessen, and, if freed, would manipulate forces against the Dragons of the continent.

Sul Khatesh's preferred form is a twelve-foot-tall hooded Humainoïde figure draped in flowing Ombre surrounded by clinging mists that obscure her features.

As with all Maîtres Démoniaques, Sul Khatesh has no true fixed form, and can assume any shape of her choosing between Fine and Colossal size.

Le Geolier of Secrets claims mastery over magic, the arcane, and secret knowledge of all kinds. Her domains are Knowledge and Magic. She is an epic-level Magicien and archmage.

<span class=“”>Though she is truly bound and only dimly conscious of the world, she can still observe standing ruins from the Âge des Démons, her chosen servants among the Rakshasa, as well as any location after her name or title is spoken for a short time.

Sul Khatesh is said to touch mortal minds even while bound by the Flamme d'Argent. She might have influenced the wizards of the Congrès Ésotérique, or had a hand in driving Mordain le Tisseur de Chair down his dark path.

Sul Khatesh has followers in Maison Orléans and the nation of Aundair.

• Hektula, the Bloody Scribe: Hektula, the librarian of Ashtakala is her prakhutu, and sits on the Conseil Sombre of the Les Seigneurs Des Cendres in Ashtakala.
• The Rakshasa Marishantar is one of her servants. He is currently operating in Cap-Tempête under a hidden identity in Maison Orléans, where he manipulates the wealthy to his mistress's ends.
