Looking back at the situation on the other side of the room, Runo continued to feel more panicked as things escalated. It seemed like there were just too many to get away from unscathed at this point, and if the others were all killed by these metallic beasts, then what? Being alone was a pretty big no in his book, especially in such a terrifying and dry place with such vicious things everywhere. *What should I do? What would I do if this was my pod?* 

...perhaps he could still do *that*? It wouldn't be fun, but it was the last option he could think of. This was an emergency! 

"Cover your ears and duck!" The merman shouted out in the hopes that he could still be heard over the chaos. If this worked, it might not have very good effects on unprotected ears. Wincing at the thought of the incoming pain, he took a deep gulp of air before releasing it in a screech powerful enough to be felt. A lot. He still didn't fully understand the solid creatures that kept shooting at them, but he had seen other Merfolk take down pretty large and scary attackers with it. It was always horrible to watch, though; there were some pretty good reasons why their 'siren screeches' were never used often. 

After almost a minute of forcing out the large sound, Runo started choking and dropped to his knees, clutching at his throat. If there way to describe the feeling left behind, he'd have to say that it was akin to having one's throat practically ripped open with hot knives. He couldn't even think past the pain at the moment to swear on how he was never going to use it ever again. Assuming that there would be an 'again', of course.
