Elsa knew from experience that drowning in a storm wasn't pleasant, but she couldn't do anything to save the crew of the latest shipwreck. She had tried to warn them, but instead of listening, they had panicked. So, she sat on a rock that was mostly higher than the waves, and, rain falling through her, sulked.
Maybe someone would survive. Maybe at least a couple of rats. Or someone else would stick around after death. That kind of company would last longest.
Maybe I should start trying to sink ships...
