Friendship and rivalry are also prominent themes. In the original stories, Harry and Draco had a complex relationship. Now, in this new setup, that relationship gets a fresh take. They may have to work together more closely like Merlin and Arthur did, but their old grudges and differences still play a part, creating an interesting blend of friendship - building and ongoing rivalry.

Adventure is another common theme, with Merlin going on quests or facing threats to the kingdom.
