Ideas to grow on #1: Ashy Waters

        The waters surrounding Riah were darker than they once were. They were cloudy, making it difficult to see or even swim through. The young Matoran shook her head, trying to think. What could have caused this? she wondered.
       She looked at the polluted liquid closely. There were small traces of what appeared to be... No, she gasped. There was, to her horror, ash. It was toxic to whoever breathed it, especially underwater. And that meant... She looked up and found multiple fish on the surface of the murky water, unmoving and on their sides. Riah closed her eyes and hoped it was all a dream... and it was.
       Riah was sitting up in her bed, eyes wide. She took a deep breath and sighed. It was just another bad dream. She wondered why she had had nightmares so often. It could be a sign from the Great Spirit -- after all, she was to be the future Chronicler of Mata Nui -- but still, this was the sixth time it had happened this night.
        She stood up and walked out of her hut, looking out at the twin moons. They shined on the water peacefully. "Oh, Mata Nui," she sighed, "why have you been giving me these dreams?"
        "Hey," a voice behind her said. Riah turned around, startled. "Er... yes, Nimera?" she asked. "Nightmares again, huh?" Nimera said. "Yeah," replied Riah. "Only they've been happening more and more lately." Nimera put a finger to her chin. "Strange. Nothing really bad has happened since the Bohrok attack, and even then, we've recovered from that... What was your dream about?"
        Riah sat down at the edge of the water. "I can't remember that much now, but it had something to do with water and... fire, I think... no, ash. Definitely ash," she said, looking down at her reflection. "Wow." Nimera sat down next to Riah. "I gotta tell you something, water and ash do not mix. Have you told Turaga Nokama about this?" "No..." "That's what you should do first. It'll only get worse if you keep secrets." "Yeah, I guess you're right." Riah smiled a little as she looked up at her best friend. "I'll tell her in the morning."
