Prince Llacheu was the son of King Arthur and Guinevere and was a minor character during the Space Camelot mini-arc for Pantheons of the NeSiverse. When Arthur decides to go into space aboard Camelot he declares his son, Llacheu, to be the new king of Britannia. With his moment of freedom Llacheu gets incredibly drunk and runs around Castle Camelot with his trousers on his head until waking up confused in the morning. He would later watch his parents sail away into the stars while he remained to rule the kingdom.
Llacheu, likely feeling oppressed by his parents, gets a moment of freedom and declares it while drunk. Upon waking up in strange circumstances he deduces that the night must have been incredible[Pan 1]. He is very dependent on his parents, and is fairly unabashedly so when he must watch his mother and father leave him behind and must be consoled by others. He is religiously minded and believes that Heaven lies in the sky[Pan 2].
Prince Llacheu's father, King Arthur, and his mother, Guinevere, decide to travel to space aboard a spaceship named Camelot. Guinevere thinks this is a great opportunity to take Morganna le Fay and her son, Mordred, away from Britannia so that Mordred wouldn't challenge Llacheu for the throne. The two parents ultimately decide this is a good time for Llacheu to learn independence and make him king of Britain. In his moment of freedom Llacheu gets incredibly drunk and runs around Castle Camelot with his trousers on his head. He wakes up in the morning handcuffed to his bed with a traffic cone. He decides this is a sign that the night had been a good one[Pan 1].
After his father managed to raise Camelot from beneath Great Britain[Pan 3], Prince Llacheu would watch the ship depart with his parents aboard from the topmost tower of Castle Camelot. Shallot, the Aes Sidhe Witch, and Vivane, The Lady of the Lake, were with him and would remain to help him grow as the new king of Britain[Pan 2].
