(Just to get in the theme :3)

The decomposing dragon roared as it swung its claws down, knocking Ruby out of the way. It wheezed as it looked at her, she was able to see that the monster had two Jaws, although one of them looked as if it was dislocated. It roared as it jumped at her, she used her semblance to run out of the way. It snapped its head at her chasing her through the vale, she was surprised and terrified that the beast was able to keep up with her using her semblance. The dragon had stopped as they had entered a narrow way. She turned back and watched it is inhaled, the clouds of gas covering its body collected towards its head. It had turned the gas into a weapon and fired it as a beam at her. It quickly came down the narrow way of the cave, her eyes widened as she tried to outrun it, but it was quickly gaining on her. Out of nowhere she was tackled to the ground as the mass of gas had shot over her and hit the wall ahead, destroying it. It was Ren who had saved Ruby

Ren: Go!

She yelled as she got up and ran into a crevasse in the wall. Ruby looked back towards the Dragon, seeing it charge her once more. She ran into the crevasse as the Dragon tried to bite her. It growled and roared as it scratched the wall, shooting a small bit of its gas at the crevasse. It stopped and glared into the hole, watching them run. It only roared in anger and had walked away. Ruby and Ren had grouped up with Weiss, Joan, Pyrrha, and Nora. They were all out of breath especially Ren. Although hers was much more severe. Her breaths became heavy as she collapsed to the floor. They gathered around her, seeing that her back was releasing the gas that was fired at them.

Nora: what's wrong with her!

They tried to wipe away the gas, using there's clothes to try and wipe it away, but it wasn't doing anything. Ruby had brought out the book, looking through it seeing if she could find an answer, she had found and read the gases name: Effluvial; a toxic gas that is fatal towards human and Faunus. But immune to Monsters other than the Hellish Fiend, only cure being known as Nullberrys. Ruby saw the picture of what the berry's looked like, she shut the book and dashed off

Weiss: where are you going!!

Ruby didn't answer as she kept running. She was having a hard time finding the berry's as there was hardly anything growing in the Rotten Vale. Ruby had entered an open area where she saw an aqua blue water, she tilted her head as she had walked over to the small lake, she was about to dip her hands in, but stopped as she noticed small bubbles. She had grabbed the book, not seeing anything about water inside the Vale. She flipped until she found an empty page, ripping it out and dropping it into the water. She watched as it disintegrated; she realized she was about to dip her hands into acid.

Ruby: God, this place is messed up, how does anything live down here.

She put the book away and looked around, until she noticed a plant by the edge of the lake of acid. She had to take the book out once more and looked at the picture of Nullberrys, and looked back up at the plant. She had found them, she quickly ran over to the berry's, but skid across the ground as the Dragon rose from the lake.
