Hello this is Snu. This is the first chapter of my fanfic.
Here are a few explanations so that no misunderstandings occur:
The unicorn is not supposed to be Lady Amalthea, but Lyra.

My fanfic should be a story that happens while the last unicorn (Lady Amalthea) leaves the forest and experiences his adventures.

The blue crystal

Evening had just come when Lyra, a white unicorn, was looking for a new place to live.
,, My sisters are annoying! Why do you always have to get on my mind? Well, now I'll find my own home. Then they will have to look for me, "thought the unicorn.
"Can we take a break? I'm pretty tired," said Fuchsie, a good friend of Lyra's, and yawned. "Or are we looking for a place where we can sleep, because it's already getting dark."
"But fuchsia, you know that I want to be as far away as we can," explained the unicorn.
"Look, Lyra.There's a cave up there. Can we take a little break in her? "
"Well, fine," said Lyra.
The two friends went into the cave and looked around it. There was nothing to be seen in the cave, except ice-cold rock walls. Fuchsia lay down on the hard stone floor and fell asleep straight away because she was so exhausted from the long hike.
Lyra did not fall asleep. She just couldn't. Maybe the moon was too bright, or it was something else. The unicorn became curious and since it couldn't sleep anyway, it had to get to the bottom before the glow. It went out of the cave and looked up at the sky. But when it saw that the sky was cloudy and the moon could not shine into the cave, it thought: "What is that? What kind of glow is that? If that is not the moon, what is it then? Or is it coming the glow from the cave? I'll get to the bottom of this now. "
Lyra stepped back into the cave and noticed that the glow was really coming from the cave.She followed him and all of a sudden she saw a small, blue crystal.
“It's a beautiful stone. Should I show it to Fuchsia? No. she is sleeping now. I'll take it with me now and show it to her tomorrow, "thought Lyra.
She took the little stone and noticed that there was something under the stone:

Crystallum magicum advertis, si eum sumis, aut calamitas fiet.

,,What does that mean? ", thought Lyra. But she couldn't understand the words. She took it in her mouth, but when she went through the cave, it didn't seem to be the same cave ...
"Where am I?" Thought Lyra.

If you want to know what the Latin sentence means and whether I should continue writing, please write me a few comments.
Otherwise I won't write any further.
