Lord Luc of House Mantear was an Andoran Royal and Queen Mordrellen's son. He was Tigraine's brother, and thus Rand's uncle, and would have been her First Prince of the Sword, had she ascended the throne (Glossary). He was tall and broad-shouldered with dark reddish hair and deep blue eyes (TSR, Ch. 33). His sign was an acorn (Glossary).
He appears in the Two Rivers under the name Luc Chiendelna, a minor Murandian noble in his middle years, with white wings at his temples and an arrogant air. He wears a golden wolf's-head buckle on his sword belt (TSR, Ch. 33).
For more information on him see the article on Slayer.
He looks like Rand's mean uncle (TPoD, Ch. 10)
He hates Perrin deeply (ToM, Ch. 37).
"Luc dead in the Blight before he was ever anointed First Prince of the Sword, and Tigraine vanished -- run off or dead -- when it came time for her to take the throne." (Almen Bunt to Rand; The Eye of the World, Chapter 34)
"Luc came to the Mountains of Dhoom.
Isam waited in the high passes.
The hunt is now begun. The Shadow's hounds now course, and kill.
One did live, and one did die, but both are."
(Excerpt of the Dark Prophecy; The Great Hunt, Chapter 7)
"After Luc rode north, never to return, whispers said Gitara had convinced him that his fame lay in the Blight, or his fate. Others said it was that he would find the Dragon Reborn there, or that the Last Battle depended on him going." (Dyelin to Rand; Lord of Chaos, Chapter 16)
