Morgana stalked through the Valley of the Fallen Kings. She was trying to find this Crystal Cave and stop Merlin just in case he managed to get his magic back and ruined her plan. When she found him, she planned on taunting him but not killing him just yet.

She was a High Priestess, for goddess's sake. It didn't matter that Mordred said that he'd barely heard of it; she would find that cave!

Many bandits later, she was so wrapped up in her search that she didn't even notice when it grew dark and she still hadn't found it.
