The Lost Species {OLD!}

Part 1-The Ancestor

There once was a pony named Glacier, who had a light periwinkle coat and light pink hair. There was, however, one special thing about her that almost nopony knew about her. She was different. There was a rare, thought to be extinct species of pony called a Nyx. They were divided into two categories: a crystophonyx, and a cycostanyx. A Nyx had special elemental powers, and each one is born with one or two of them. All of the known powers were ice, nature, water, wind, snow, and lightning. A crystophonyx was like a crystal pony with elemental powers, and a cycostanyx was one with nightmare powers and that contained a substance called nightmarium. A Nyx also had a crystal on their chest that they referred to as their core, or their gem. It was like their heart, and contained energy for them to use those powers. Glacier had ice powers and the job of assisting Equestria with creating winter, but nopony else knew about this except for Princess Celestia. She was thinking about promoting her to the winter guardian, but she hadn't really acted upon it quite yet. One day, while she was creating winter, there was an avalanche. Glacier ran into a cave and fell into a much deeper part of it. She had fallen on her wing, so she couldn't do much. Her gem had also cracked, so she couldn't do much with ice. There was no use. She was stuck, and this cave was too far from Canterlot to ask for help. While she was in the cave, she fed on mostly snow grasses. Guess you can't starve for a winter, right? Some rescue teams had also checked the area, but she was too deep. She climbed up to the higher part of the cave and tried digging at the hard packed snow. She got halfway through and after spring, she was finally out. Glacier didn't really get cold because of her powers, but she was still a pony. She fainted in front of the cave. When she finally came to, she was very confused. "Oh, you're awake. Hello." She was on a carpet in front of a fireplace. "W-w-where am I?" She looked up and saw a purple unicorn. "I'm Twilight Sparkle. I found you in a pile of snow and took you in. This is Spike. Spike, she needs more blankets." She tried flapping her wings. "You fractured your wing somehow."
"I don't understand...did I overdo it? What caused that avalanche?"
"Overdo what?"
"Winter."
"Are you trying to say that you make winter? Because that would be-"
"Yes."
"How?"
"I have certain...abilities." She made an ice snowflake. "Whoa! That's so cool! How do you do that?"
"I'm a different breed of pony. A crystophonyx."
"I have to do research on this!"
"No, no no no no. No research. I'm not a guinea pig." She shivered a bit. "Thank you, but I should really get going." She tried to walk, but collapsed. "Your hind leg and spinal cord were injured somehow. You're grounded and immobilized."
"(Sigh) Do you ever have any good news?" There was a knock at the door at Twilight's Canterlot home. Twilight told the visitor to come in, and found out that it was Princess Celestia. "Oh, good morning, princess. Do you need anything?" Her mouth was wide open and she was shocked to see Glacier injured on the floor. "What happened?" She said, distraught. "I was making winter and there was an avalanche, so I ran into a cave. I fell into another cavern, and after about a season or so I finally got out."
"A season? A SEASON?! Those foolish rescue workers can't do anything right!"
"Celestia...don't blame it on them. It was my fault for running into that cave." She hugged her. "Don't blame it on yourself, either. I blame it on that avalanche. The Canterlot mountains don't get avalanches. I wonder if it was created."
"What? Who would-" She knew who.
"I don't know. I'm just glad you're safe." She smiled at her. "Thank you, Twilight. You have saved my dear friend."
"I didn't know how important she was to you."
"You're always so busy with work. You should make friends."
"But princess, I-" Before she could get that word out, they were gone.
"Ugh."
