King Ulthas Ardignas was the third king of Kandarin and a popular and loved ruler. He was the father of King Lathas and King Tyras. When King Arthur and the Knights of the Round Table arrived to Gielinor from Britain in 5.132, they found that he required a castle or fortress to call his own. One such castle was found east of Seers' Village, but at the time it was owned by Lord Sinclair and his children, who were all very young at the time. King Ulthas and Lord Sinclair decided that King Arthur's need of the castle was greater than the Sinclair family's, and so Lord Sinclair and his family left the castle and moved to Sinclair Mansion to the north (much to his children's displeasure). King Arthur claimed the castle and renamed it Camelot.
