Merlin watched for a few more minutes and watched the clouds, but they clearly weren't going to move, so he finished his bread roll and stood up, pushing up his sleeves and then flexing his fingers.
"Right." He voice thrummed with power as he started to gather his magic to him. He pushed his hands out, creating a diamond between his thumbs and forefingers over the place on the horizon he wanted to clear. "And for my next trick," he said, and started speaking words of power, his eyes at first flashing gold, then glowing with the lights of the universe.
Slowly on the horizon, a wind picked up and the clouds started to move.
