Silvester de Ruiz was a prominent vassal of the Sea of Shadows and former Lord of Iberia. The youngest of the clan to ever sit in judgement with the Amici Noctis, he was killed by his childe in 1424 CE.
His only known progeny was Ambrosio Luis Monçada. Silvester Embraced him while Monçada was acting Archbishop of the Central Church of Madrid, Spain, as Monçada's compatriots were regular visitors to his confessional and patrons of priests.
One of his havens was inside the Lasombra Antediluvian's domain, the Castel d'Ombro. He was killed by a coup organized by Monçada in 1424. Some observers view this as an opening shot fired in the Anarch Revolt.
