Arriving in Camelot

Merlin is Prince of Ealdor. Uther and Ygraine rulers of Camelot have invited Merlin to their kingdom for the first time in years. They invite him in the hopes that Arthur and Merlin will fall in love and their betrothal to bring the two kingdoms together will finally be fulfilled. There's only one problem...Arthur and Merlin don't know about the betrothal.
