Clash of magic

You may have heard of a different story of which a young warlock became the servant to a prat. That prat ended up becoming the king of all Camelot. Some might even say that the two young men became the best of friends. You can believe this, I will not stop you. But today I am going to tell you a story of which the young warlock is the loving king of the druids. The king is lonely, even if he has much. Let me change your view for a small while. Welcome to the castle of Camelot.

To my fellow Merlin fans, some rules:
1. Merlin and Arthur never met.
2. Merlin got married to Freya.
3. Merlin is king of the druids.
4. Arthur is still king and married to Gwen.
5. Both have children:
A. Durwin, 17, Red head, Sophisticated
M. Thea, 18, Brown hair, rustic
6. All round table nights are alive, Including Mordred who
did not become bad
7. Arthur is accepting of magic but it is still not completely legal
8. The knights are split in two:
Merlin has Gwaine, Lancelot, and Mordred
Arthur has Elyan, Leon, and Percival
