Unlike Emilia, Lystra had a bit of trouble with the water. While she wasn't a terrible swimmer, she definitely wasn't the best. Plus, trying to keep her eyes open while under? That was something she hadn't tried before, and the water stung as she fumbled a few moments but managed well enough to keep her eyes on her friend and stay moving. What she saw barely a minute later, completely changed her attitude about what she was doing. Normally she'd just pass off Emilia's nonsensical discovers as just that, even if she liked to think they might be something different, but this? Lystra's eyes opened wide against the cold, stinging water as she saw what was obviously a man made door. She had seen similar structures in ruins above ground on occasion...but why was it here underwater? That was her first question. Did whoever build it have to swim here to get in? Or perhaps the lake wasn't always here or something? She pushed the questions out of her head for now. She had no way to know, and her lungs were starting to strain so she picked up the pace, following after Emilia the best she could. The curved tunnel prove to be somewhat difficult to traverse for her. While not completely unathletic, she had never swam that much. She had to be careful of the rocks on the wall, trying her best to mimic the motions of Emilia as they swam. It was...easy enough, if one could count tearing her tunic on a small outcropping as little trouble. More importantly, where the hell was Emilia taking them? She wasn't sure how much longer she could hold her breath. The surface came suddenly, with Lystra breaking the surface of the cave with gasping breaths of air next to Emilia. "Next time," She coughed through gasping mouthfuls of air. "Warn me I need to turn into a fish to get somewhere..." After a few seconds, she was able to get a good look at the room...and she was absolutely amazed. "By the Elements though...this place...what is it?" Lystra swam a little ways from Emilia. It was absolutely amazing. She had always been fascinated by places like this - there was something about old ruins and walls that was just...alluring to her. She looked around for perhaps somewhere they could get out of the water...was there any more to this ruin, perhaps?
