Considered the founders of Semberholme, members of the Ulondarr clan have devoted their lives to maintaining Semberholme, following the appearance of the avatar of Corellon to their ancestors thousands of years ago. While some Ulondarr families can be found in Myth Drannor and Old Elven Court, the majority of them call Semberholme their home. Since the Ulondarrs freely offered their administration of Semberholme, few others stepped forward to share the responsibility.
