After Arthur was crowned king he removed into Wales, where he gave orders that a great feast should be held on the coming day of Pentecost, at the city of Carlion. On the day appointed for the feast there appeared before Carlion the Kings of Lothian and Orkney, Gore, Garloth, Carados, and Scotland, each with a large following of knights. Their coming greatly pleased King Arthur, who believed that they desired to do honor to his reign, and he sent presents of great value to them and to their knights. These they disdainfully refused, sending back a hostile challenge by the messenger, and saying that they had not come to receive gifts from a beardless boy, of ignoble blood, but to present him gifts with hard swords between neck and shoulder. It was a shame, they said, to see such a boy at the head of so noble a realm, and this wrong should be redressed at their hands. On receiving this defiant message, Arthur threw himself, with five hundred good men, into a strong tower near Carlion, for he was ill prepared for attack. There he was closely besieged by his foes, but the castle was well victualled, and held out stoutly against its assailants. During the siege Merlin appeared suddenly among the kings, and told them privately who Arthur really was, assuring them that he was of nobler blood than themselves, and was destined long to remain king of England, and to reduce Scotland, Ireland, and Wales to his sway. Some of the hostile monarchs believed the magician's story, but others doubted it, King Lot of Orkney laughing him to scorn, while some among them called him a prating wizard. But it was agreed that they should hold a conference with Arthur, they promising if he came out to them to place no hindrance to his safe return. Merlin then sought the king and advised him to accept the conference, telling him that he had nothing to fear. Thereupon Arthur armed himself, and taking with him the Archbishop of Canterbury and several noble knights, went out boldly to meet his foes. The conference was an angry and bitter one, the kings speaking strongly, and Arthur answering them with stout words of defiance, in which he told them plainly that if he lived he would make them bow to his throne. In the end they parted in wrath, the kings returning to their camp and Arthur to the tower. "What do you propose to do?" said Merlin to the kings. "If you take a wise man's advice you will withdraw, for I tell you that you shall not prevail here, were you ten times as many."
