Colours in Shadows: Book 1 Flooding and Fury

"Ugh!" Sapphire growled, as she marched up the hill that the Spirit told her to go to. "There's only one way up and one way down." she said to herself.
The hill was tall and she was only about halfway up. 'I like an adventure once in a while but I didn't expect to be climbing a hill! Who was that Spirit dude anyway?' she thought. "I must get to the top and see what this adventure is all about!"
She finally reached the top and looked around, wondering where this Spirit could be. 'Where is he?! He said he would be here... this had better not be some trick!'
Suddenly, she noticed a blue figure standing just in front of her. "A SEA SERPENT?!" she yelled, creating a fireball and preparing to throw it. The blue creature looked down at itself and then looked back at her.
"I wouldn't really call myself a sea serpent, but alright." it meowed, sleepily. It was night before Sapphire had reached the hill.
The voice was deep and she was realizing that he was a cat like her. But he looked strange. His whole body was covered in short, blue fur. He had four, pale blue dots under his left eye and a tuft of hair that cascaded almost entirely over his right. He looked very fit.
"Who are you?" she asked, suspiciously. She carefully lowered her paw, the fireball disappearing as she did. She still stood there, prepared to bring it back if she needed it.
"I was about to ask you the same thing." he said, his blue eyes looking at her. He appeared just as suspicious as she was.
A white cat came rushing over, unexpectedly. "Please don't hurt each other! We should be as peaceful as possible." she mewed.
"You should be especially careful if you can shoot flames from your paws."
Sapphire gave her a strange look, seeing her purple eyes in the dark. "And who might you be?" she said, sarcastically. She was getting tired of asking the same question and not getting an answer.
"My name is Misty." she mewed, cheerfully.
While they were talking, a brown cat emerged from a short distance away. He appeared confused and was much smaller in size than the rest of them.
"AND WHO ARE YOU?!" Sapphire yelled.
The brown cat froze and stared at her. Sapphire looked at him strangely. Just as she was about to say something, she heard something behind her. She quickly turned around, preparing to throw a fireball at the sound. The other cats prepared themselves to do the same. The blue cat looked like he was going to throw something as well. It wasn't fire, it looked like...

'Water?'

The brown cat that had just showed up was surrounded with vines. They weren't there before. Misty looked like she was holding her breath. Sapphire rolled her eyes. A sarcastic thought popped up from the back of her mind: 'Misty is scared of an argument?'
The thought disappeared quickly because when Sapphire looked in front of her, she realized...
