Rizzen Do'Urden was a patron of House Do'Urden and fathered several of Malice's children.
He was the patron of Matron Malice Do'Urden until his death, in which Malice tricked Rizzen into engaging the spirit-wraith Zaknafein in a fight, when he was promptly hacked to pieces. Malice claimed that it was no great loss as she had already chosen her next patron from amongst the soldiers of House Do'Urden.
Rizzen was also the patron of House Do'Urden at the time of Drizzt Do'Urden's birth, though it was common knowledge that he was not the father of Drizzt. Rizzen Do'Urden was the known father of Nalfein, Dinin and Maya.
