As you've probably worked out, this fic has been discontinued. Here are some extras (a half-finished chapter and my plan for the rest)
CHAPTER 10: Fire
It was so… sodden in here. Utterly damp. Ashen supposed that it should be expected, considering that it was behind a waterfall, but it didn't make it any less unpleasant. The water clung to her fur, eroding her strength, and they were constantly faced by moats which they could not navigate. At least they hadn't met any water-types yet, but she knew that they would soon, and that they could draw their strength from all of the water around them.
They were on floor two when the vulpix heard a splash and felt her entire body get soaked. Instantly she felt weak, dizzy, almost passing out. She turned to face the foe, violently trembling, and saw as Flo hit them with a powerful scratch from stubby claws. The blue, slimy, frog pokémon poliwag did not run off, even though it was about to collapse. It readied itself for another shot.
Ashen thought about using her fire, but it seemed like a bad idea. She leapt to the side slightly too much, almost landing in the water, and then bounded forwards. Once she reached the poliwag she wasn't sure really how to do this, so she just hit it in the face with her paw. It fell backwards, unconscious.
"Nice!" Flo commented, "At this rate we won't need torkoal at all."
Ashen didn't reply, but she smiled.
They continued through the corridors, peering glumly at the various water-bound flora and, occasionally, fauna. Nothing looked like it would burn very well, Ashen wondered if Torkoal knew a way to overcome this. She tried gently blowing some flames onto the water surface, but again it was just the uncontrolled fireball. Steam rose from the water and she couldn't see, not even Flo.
"Sorry." She mumbled, "it's easier than the other way to make a smokescreen, but that wasn't good timing."
When the fog cleared, Flo looked more fascinated than anything else.
"Isn't it fascinating how fire can defeat water? I know you're weak to it, but if your body temperature was high enough then all of it would just boil off you like steam. I wonder if there's a pokémon somewhere that's hot enough to withstand every water attack."
"If you're that hot…" she searched for something she felt nagging in the back of her head, an idea considered once, "wouldn't too much water make you cool down, crack, and harden?"
"I suppose, like lava."
She briefly thought about whether having the fire brewing in her belly raised her body temperature, and whether that could ever be high enough to withstand the poliwag's water jets, but it wasn't worth too much thought.
When they met a group of hostile water pokémon at a dead end Ashen released her fire and caused a cloud of steam in which they escaped.
