Outside of the castle, Arthur is seen riding in his huge warhorse and stands with his assembled forces and a mysterious cloaked person who stands beside him. When Hendricksen confronted Arthur outside of the gates, the king of Camelot wishes to be granted audience with King Liones after the cloaked person removed an illusion of an army revealing it to be a ruse just to get the Holy Knights' attention. Hendricksen lied to Arthur, saying the king was sick and is under care of the kingdom's finest mages, but Arthur told the latter that his cloak friend can heal him. Hendricksen refused Arthur offer, but the latter said he refused to leave, and if there is a problem, he would help out.

Hendricksen reluctantly accepted Arthur's offer and escorted the king of Camelot and his cloaked friend to the castle. While on the way there, Hendricksen questioned Arthur if he knew of the problem they're facing only for the young king to reveal that he made it up, making the Great Holy Knight grew suspicious of him. Asking Arthur once more, this time of what he's after, only for the latter refuse to reveal it, Hendricksen and his two other Holy Knights surrounded the duo and told them that they killed every foreign messengers who visited Liones, even if he was the king. Then suddenly, an unnamed female Holy Knight appeared out of nowhere and informed Hendricksen of a event and teleported away. When Arthur asked if the female Holy Knight was a Liones mage, Hendricksen immediately attacked Arthur with one slash, telling him that he won't live to find out.
