That what only one should do

“I got it I guess, Aline. I’m not exactly sure, because there are quite a lot of words that I simply do not understand, but I guess it says something about everyone being able to open the door, but only the one that should can go to the place the doors lead to.” Twinkle Star said while she got up.
She had been inspecting the stone for half an hour now and this was the only thing what she could make of it. She missed quite a lot of words here and there, but there didn’t seem to be any other option on what these other words could mean. “okay, now that doesn’t get us very far, does it? What does it mean anyway?” Aline said annoyed.
Twinkle Star was a bit annoyed and disappointed, too. She had hoped to find the way in, but this didn’t help at all, even though she vaguely had the idea she had heard this before, somewhere. But it didn’t tell anything about how they had to open the doors.
“I suppose… I suppose this isn’t just a door. You see, everyone can open it, but when the right person opens it, it will lead you to something else, to what truly is behind the doors. Old magic I guess.”
“It leads to two different things? Is that even possible?” Aline asked.
“Yes. You can link a door to a different place with old magic, or something like that. I don’t really know either but I heard of it before. It was lost long before our time though. But I guess this is one of those old doors.” Twinkle Star answered and Aline sighed.
“Maybe we just should go back, cross Fiume, and try to go to the other side. Face it, we’re not going to get anywhere here, Twinkle.” Aline said while she got up to pack her stuff.

“Wait! Say that again!” Twinkle Star said excited while she jumped up. She somehow got closer to remembering where she heard these words before. Something Aline said had triggered a memory that she had almost forgotten, but she couldn’t really figure out what it was exactly. Aline looked at her in a silly way.
“Go on, repeat what you just said!” Twinkle Star asked, impatiently.
“I said, we have to go back to Fiume, cross it, and…”  Twinkle Star jumped up again. Of course, that was it! How could she have forgotten that!
“Fiume! Of course! Fiume told me this! Aline, we’re on the right track!” Twinkle star said excited and Aline stared at her as if she had gone crazy.
“The river Fiume? You mean, the river told you something? As with words? You feeling okay?” She said with a concerned voice.
Twinkle Star laughed. “Yes, yes I’m fine! Fiume is a river with a soul Aline, and it might tell you things when your powers are strong enough, just as it has purifying powers and everything. It has told me more things than that, in fact it is the reason I am actually here! But I’ll explain that to you later, it’s not that important now! Shortly before I left my aunt to go to this place to find my sister, Fiume told me that there are things anyone can do, things only one can do and things only one should do. You see? Things that only one should do! That’s what it says on the stone! The river told me about this place!” she said excited.
 Twinkle Star noticed Aline still didn’t completely believe her, but apparently she had decided to play along for now, as she didn’t object to what Twinkle Star was saying.
“Okay… so we know the river told you about this door, probably. Means we’re on the right track, as you said. But who is the one that should open the door, and how? It didn’t say anything about that, did it?” Aline asked.  
Twinkle Star sighed and she felt her excitement fading away. Aline definitely had a point with that. “I don’t know. I’m pretty sure it doesn’t say anything about that on the rock, and no, Fiume didn’t mention it. It didn’t even mention the doors or anything, actually.”
 Twinkle Star looked at the doorway. There had to be a way in, she was sure of it, and either she or Aline was the only one who should open it, so they could go to the place the doors truly lead to. She looked at the stone, back to the doors and then back to the stone. Suddenly she laughed. How could she have been so stupid!

“What’s there to laugh about?” Aline wondered.
“It’s so obvious! It’s so obvious and we didn’t see it! You see that mark of a hoof on the rock? We have to place a hoof on that stone and then I guess either the door will open or something will happen that shows us how we can open the door.” Aline sighed. “Right. But who has to open the door? If what you told me about the river is true, it means it’s probably you, but we have to be absolutely sure, because otherwise we won’t find what we are looking for!”
Twinkle Star didn’t say anything for a while. Aline was definitely right and she wanted to be sure the right person opened it. Considering the fact that her family symbol was on the door and she was the one with the royal powers, the obvious choice would be her, Twinkle Star, but something bothered her. Something didn’t feel right. If it really did require something special to open these doors, it wouldn’t be about just royal powers. Something else was required to open these doors, but what?
Then what about the prophecy? Twinkle star suddenly thought. Aline was the winter in the diamond’s eyes so there had to be something special about her, Twinkle Star was sure of that.  And she hadn’t figured out Aline’s part in the prophecy. She repeated the prophecy in her head a few times. “In the word where everything is lost, go find the winter in a diamond’s eyes, unlock the tear in your soul and the future of the lands that are lost will be revealed.”  Right, she had to find Aline before she opened the door. She sighed. It was risky, but somehow it felt as if this was the right decision.

“You do it, Aline.”
Aline looked up. “Why me? What made you think that?”
 “Well, you are part of the prophecy. I had to find you before all else. Nothing points to me having to open it. Put your hoof on the rock, Aline.” Twinkle Star explained.
She still didn’t really know why she wanted Aline to do it because if she had to be honest, she felt that she had to open it, as it was her family’s symbol on that rock and those doors. But something deep in her said she shouldn’t be selfish about this, that this was Aline’s part in this story.
 “What will happen if we were wrong?” Aline asked.
“Nothing serious, I guess,” Twinkle Star answered, “I mean, it said so on the stone. Anyone can open it. All I’m afraid of is that the place it would lead to if we are wrong is buried under a few feet of rocks and congealed lava.”

Slowly Aline walked towards the rock. For a while she stared at the rock.
“Are you sure?” She asked Twinkle Star one last time and Twinkle Star nodded. Slowly Aline raised her hoof, which was shaking a bit as she was quite nervous about it, and placed it on the rock. At first, nothing happened. Twinkle Star began to wonder if she really had been right about this, but then a light appeared from underneath the stone, and the symbols of the royal family and the friendship lands lit up, together with the ancient text. With a loud noise the doors shove to the side and disappeared in the walls beside them, to reveal other doors behind the old ones. These doors looked very different. They weren’t old or rocky, they weren’t even cracked or damaged. They were white with silver markings on them. Silver curls and swirls were painted all over the nice white doors and all these appeared to originate from a small hole at the pony’s shoulder height right in the middle of the doors. While Aline kept her hoof on the rock and stared in amazement to the doors, Twinkle Star smiled. She had done the right thing, she was sure of it now. It was Aline who had to put her hoof on the rock all right, even though she didn’t really know yet why it had to be Aline. These doors definitely didn’t appear before just anyone. Slowly Twinkle Star walked towards the doors and looked at the little hole out of which all the silver curls appeared to originate. The hole wasn’t deep, only about two inches, and it was a round circle. It was just big enough for a pendant to put in while standing upright. The back wall of the hole wasn’t white rock as the doors were, but it was made out of some kind of weird stone that had a different color every time you looked at it from a different angle. Twinkle Star recognised the hole for what it was in an instant. This wasn’t just a damaged part of the doors or decoration, it was a lock. In her old castle, the doors of the more important rooms, like the throne room or the queen’s bedroom had a lock like this. They responded to a pendant and naturally, in the royal castle most locks only responded to the royal pendant, and Twinkle Star knew this was her part of the prophecy.

“What are you doing?” she heard Aline ask when she took of her pendant. “Aline… there are some things only one should do, but this is one of those things only one can do.” She answered in a bit of a mysterious voice while she placed her pendant in the hole.
The second the pendant was in its place a light appeared in the hole and the doors began to open slowly to the inside. Twinkle Star took her pendant out of the hole and placed it back on her neck once again. Meanwhile Aline had taken her hoof off the stone and stood next to Twinkle Star with their bags.
 “What did you do?” She asked.
“Opened the door with my pendant. It can only be opened by a royal one, just as the more important doors in my old castle. This as well is an example of the magic of the royal family. But I was right all along, Aline. It was you who was the one who had to open these doors. Doors like this don’t get revealed to anyone, this is truly what the earlier doors were hiding.”
Aline stared at Twinkle Star. “Then why was it me? What do I have that made these doors appear?” She asked.
“I don’t know. Not yet, anyway. Maybe we will find out once we are inside. I guess there is more to you than we both first thought, Aline. But we are on the right track, I’m sure about it now.”
“You think Stelline is in here?” Aline asked.
“I don’t know, but if she isn’t, we’ll definitely find a clue on where or how to find her.” Twinkle Star answered while she took her bag from Aling and flung it around her neck. Meanwhile the doors had opened completely. There was a long hallway before them and when they heard the final bang of the doors hitting the walls, torches began to be lit. First the ones close to the doors, but they saw torches being lit further and further until it was too far way for them to see. The torches were a little above their heads, and they were neatly placed to the walls in nice dark-green holders.  
The hallway was beautiful, even though the walls also had their share of cracks from the eruption, but overall, this place appeared to be in quite good condition. Twinkle Star figured this had been protected by some old magic that had been forgotten long ago. She couldn’t remember that she ever heard about the existence of this place, but when she thought of what it probably was, it wasn’t weird that nobody ever told her.  While the floor was made of gold-coloured tiles that looked as if they had been cleaned only seconds before as you could see your own reflection in them, the walls were made of the same white as the door and they had the same silver swirls on them as the doors had, only these appeared to be drawn randomly instead of going to a certain point as the ones on the door had done. Between the torches on each side of the wall there appeared to be a painting. The ceiling was painted in a nice dark blue colour, but Twinkle Star noticed the ceiling had more cracks in it than the walls. She sighed. Even an ancient place like this hadn’t been safe from the forces of nature…

“Twinkle Star, what on earth is this place? What is up with those silver curls and everything?” Aline asked in amazement, as they slowly walked through the doors. Twinkle Star smiled while she looked at the swirls closer and she noticed how neat they were painted. If it wouldn’t be for the cracks in the walls, it would actually be something that came close to being perfect.
“Those swirls... Aline, this is the sign of the unicorns.”
