She woke up with a start. She looked around to find she was in a big, dark room. She went to get up to see where she was, but her two hind hooves were chained to the wall. She tried to use her magic to unlock them, but then remembered her black horn. She put her hoof in front of her face. It was black. She looked on each side of her to find Stormcloud and the other unicorn. She smiled and started run towards Stormcloud. When she was about a foot away, the chains stopped. She wanted to see if Stormcloud really was dead, or only unconscious. She walked over the other unicorn. He was rolled close enough for her to reach. She laid her head on his head and felt a pulse. She sighed and smiled. She started to shake the other unicorn awake. His eyes opened and she looked at him. The unicorn clutched his forehead.
"Where are we?"
Sweetie Belle shrugged and said, "Your guess is as good as mine. I'm Sweetie Belle."
"Night Crest."
"I know what happened, but it's kinda hard to explain."
Sweetie Belle told Night Crest about the day she had and the black horn.
"So, what about that other unicorn?"
"Well, his name is Stormcloud, but I sometimes call him Stormy, and he has risked his life far too many times for me and I am afraid that he may not walk away from this."
"Do you know a reverse spell for the black horn?"
"What do you mean?"
Night Crest pulled out a notebook and flipped through the pages.
"I've kept a book of all the dark magic I know of. I think I've written about black horn before."
He stopped at a page near the middle and pushed the book over to Sweetie Belle. She looked at the pages, hoping to find information to help them. She saw that there was no reverse spell. There was an interesting picture that caught her eye, though. It was a picture of unicorns with black horn in front of this great monster. The monster was so black that Sweetie could only see it's outline.
"What is that thing?"
"A shadow dragon. I know that they are very territorial. We must have stepped into it's territory when we all got black horn."
"Then, are we in the shadow dragon's lair?"
As she finished the sentence, the stones in the wall collapsed on them and Stormcloud. Sweetie Belle and Night Crest climbed out of the stones and ran to where Stormcloud was. She started to throw stones crazily, hoping to find Stormcloud alive. She remembered the chain and started to bash the cuff around her hooves with the bricks. They came of and she continued to dig. She saw a glimpse of his blue and green hair. Sweetie Belle started to dig faster. Night Crest saw and bashed off his chains. He went over to Sweetie Belle and helped her pull up Stormcloud. The shadow dragon started to knock down the other walls. They quickly pulled out Stormcloud. Sweetie Belle grabbed Night Crest and held him to her chest and hovered over Stormcloud as the bricks and dust came crashing down over them. Night Crest and Stormcloud were both saved from the rubble while Sweetie Belle took all the blows. Her back was being cut into by the shrapnels from the bricks. She squeezed her eyes closed tight and held Night Crest closer. She knew that if Stormcloud and herself died, Night Crest would not be able to survive because he was much younger than both of them. When Sweetie Belle thought the stones stopped piling on, Stormcloud woke up.
"Where are we?"
"No time to talk! I'm Night Crest. Sweetie Belle needs our help! Maybe we can combine the little magic we have left to create something!"
They all put there horns together and thought the same thing. A swirl of all of their colors of magic, green, blue, and purple, started to surround them. Sweetie Belle collapsed, but the bricks did not fall. They had created a force field.
