Ulondarr House Ulondarr 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 . Vesperr Ulondarr , a kind and benevolent elf who loves elven children more than anything else on Faerûn has led the clan for centuries . Most of the Ulondarr clan share Vesperr ’ s affection for the young , but none more than Vesperr himself . His duties to the Council of Trees has often been preempted by his hours of storytelling beneath the Tree of Knowledge . Since the Ulondarrs freely offered their administration of Semberholme , few others stepped forward to share the responsibility . This is partially due to the fact that most families did not stay in Semberholme more than three decades , and few especially power - hungry golds saw the need to control a community with no redeeming value in the political scheme of things . The Ulondarrs are doing an excellent job in Semberholme as far as all elves were concerned . After the location of Semberholmme was agreed upon , the task of preparing the location for the elves fell to the hands of the Ulondarr Clan of moon elves . While inspecting the site , the members of the Ulondarr clan reported coming into contact with an avatar of Corellon Larethian . The avatar stated that Semberholme would be a place of peace where all elves are welcome . The proclamation also came with a warning that if elf slew elf within the forest of Semberholme , the elves of Cormanthyr would be banned from Arvandor for all time . The decree was passed on to all elves of the land , and from then on the Ulondarr devoted their clan to the wishes of Corellon and Semberholme . Though a community of mostly non - combatants , the elves of the Ulondarr Clan had foreseen the possibility of invasions centuries before and formed the Moonshadows , an elite group of warriors and wizards devoted to protect the innocents of Semberholme . Between the Moonshadows , the limestone caves , and other creatures of the forest who aided them , aggressors were typically slain before even coming close to Semberholme . Tel ' Kiira While all the noble families of Cormanthor once had an active family kiira , the only clans at present that acknowledge the existence of a family kiira are these : the Alastrarra , Aunglor , Durothil , Haevault , Iliathor , Neirdre , Nimesin , Orbryn , Raedrimn , Starym , and Ulondarr . Noble Families of Cormanthyr The noble Houses of Myth Drannor have varied greatly across the millennia since the first priest arrived at Elven Court during the Crown Wars . By Myth Drannor ' s time , 48 Houses had risen and fallen since the time of Arcorar , and the oldest Houses that remained were the clans of Durothil , Irithyl , Nimesin , Echorn , Starym , Dahast , Ongluth , and Mistwinter ( in order of seniority ) . These , along with the younger Clans Eaoleth and Ulondarr , are the 12 First Houses of Cormanthyr . Though conservative and overprotective , Vesperr ' s decisions prove to be popular among all the clans of Semberholme . Noble Villa : House Ulondarr .
