The blade was plunged into a stone so familiar I had to use a good chunk of my willpower not to laugh out. It was the same stone that the blade was in when Merlin tricked Arthur into believing himself to be a proper king. That only a true and good king could pull out the sword. The promise of that sword had already been placed and everyone in the world knew of the legend of Excalibur at that point. How an Archfey’s promise could alter reality was always mind boggling to me. When that promise was made, I wasn’t sure it would work. Avalon hadn’t been created and Excalibur was one of the first most powerful promises I had made at the time.
