"I do understand that. Now, how to explain..." Ivy sat next to the pool, considering, and then sighed. "You are very different from elves, humans, and most other creatures, Alrea. As a water elemental, you have complete control of your body. You can change shapes and learn very fast. But, you saw how the water wore away at the stone, yes? My body is like that, in some ways. If something breaks my skin, I can't easily repair it. It's...not permanent, but it takes time to heal. Or plants can dig through earth...tiny organisms, like grass and the like, of sorts, can invade my body. They make it work badly. It can even<em>kill</em>me, under bad situations. The creature that attacked me in your lake? It did something that attacked my body, and my mind started to...not work right. I couldn't think properly. It took them this long to fix it. Does that answer the question?"
