Helion

High Lord of the Day Court, a being of radiant charm and ancient knowledge who hides the sharpest mind in Prythian behind a smile of pure sunlight.

Also known as: Helion, Lord of Day, the Sun Lord, the Scholar King, the Radiant One, the Smiling Lord

What They Know

Knows the contents of every major library in Prythian, including texts the other High Lords have forgotten exist.
Understands the language of the Book of Breathings better than any living fae — he has studied its fragments for centuries.
Has a working theory that the Dread Trove is not three objects but four, and that the fourth was deliberately erased from history.
Knows that the King of Hybern has been buying information from a source inside the Day Court for at least three decades, and has not yet caught the traitor.
Suspects that the mating bond is not a random gift of the Cauldron but a deliberate mechanism — a kind of key — and that its true purpose has been lost.
Has met the Bone Carver and the Weaver, and made bargains with both that he has never spoken of to anyone.
Knows that Rhysand's mother was a scholar from the Day Court who fled an arranged marriage to Beron's brother, and that she carried secrets Helion still wants.
Has a private collection of maps of the continent before the Wall was raised, showing territories that no longer exist.
