Szwentil Illeon was the wealthiest man in Marsember, Cormyr. He was one of the six founders of the Six Coffers Market Priakos, owner of The Roaring Griffon and was rumoured to be worth over six million gold pieces. He was so wealthy that he was able to buy enough of anything to manufacture a shortage, although he prefered to avoid doing this to remain somewhat anonymous. He was rumoured to be involved in smuggling. Szwentil lived in his private residence, Stormwinds Towers, and was always surrounded by bodyguards, including battlemages.
Szwentil was slim and youthful in appearance, and always dressed neatly in black.
