What do I do?

Do I tell Arthur to let magic into Camelot?

If I do that then Mordred will live, the dragon said I must let him die.

I want magic to come to Camelot, it is what I've always wanted. If I say that then Mordred will live, he will play his part in killing Arthur.

I can't let that happen.

I have to keep Arthur alive.

It's my job.

I'm sorry but I can't let the man who is destined to play a part in Arthur's death live.
