Agatha and Tedros, meanwhile, have found King Arthur's ring (which can keep the Storian alive), and they use Wish Fish to find Sophie.

Later, Tedros also learns that Japeth and Rhian were not King Arthur's sons and that their true parents are still unknown.

With Excalibur's new challenge in mind, Agatha, Hort, and Nicola set off with Tedros to help him achieve the first test, and in doing so, find a version of Merlin turned into a baby.

However, Merlin manages to revive Tedros with a Wizard Wish from the Lady of the Lake, and the results are shown to be a mistake after Agatha and Sophie steal the fabric from Japeth and incinerate it, with the sword returning to the stone.

Japeth, it turns out, had murdered Lady Gremlaine's son Chaddick, who was Tedros' half-brother (unbeknownst to King Arthur and the rest of the society in the Endless Woods); he had then used Chaddick's blood to trick Excalibur and Camelot's crown into believing that he was the true king.

For example, there was a game called Escape the School in which guests participate in a trivia exam about the books, with the highest scorer winning a Nintendo Switch.
