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.
King Ulthas had two children, named Lathas and Tyras. He declared that his kingdom be split equally between them after death, including the division of its capital Ardougne. Ulthas was killed in a hunting accident in the surrounding forests in 136, after which his two sons each ascended their half-thrones.
Lathas, however, was unable to tolerate what he viewed as the expulsion of the Sinclairs in favour of King Arthur and was dismayed at being denied his birthright by having to share the throne with his "idiot younger brother" Tyras. As a result, he vowed to re-unite Ulthas' kingdom under his own reign and allied with the malevolent Iorwerth Clan of elves to do so.

- Ulthas' name may be a reference to Uther Pendragon, father of King Arthur
- His death is similar to that of King William Rufus who was killed by a stray arrow whilst out hunting.
- Ulthas' story has a striking resemblance to A Song of Ice and Fire. King Ulthas' predecessor, King Narras (Aerys Targaryen), was a mad king, killing innocents for no reason whatsoever. King Ulthas (Robert Baratheon), King Narras' successor, was killed in a hunting accident and his heir was controversial.
