The House of Syldavia or Syldavian dynasty and sometimes referred to as the House of Endralon, is a prominent Artanian royal house of Endralonian origin that rules the Kingdom of Endralon. The Syldavian family rose to power in the wake of the toppling of the Fortenohfiv dynasty and the subsequent Endralon Civil War, which left the House of Fortenohfiv extirpated.
