"Do you have an idea on where to go, Amethyst?" Sweetie Belle asked. The colt looked at the hundred of tunnels, and wondered on how to answer.
"Um," He continued on thinking. "what if the right tunnel is the one filled with more crystals and gems?"
Sweetie Belle was about to hoofpalm herself again, but instead answered his assumption.
"This sounds dumb, like, why would the right tunnel be the most crystal-like? And also, why would you think like this?"
Amethyst felt akward. This time he failed on giving an proper explanation on his assumption. Sweetie looked at him with her green eyes.
"Do you know a spell that exposes gems from the underground..?" Amethyst slowly asked the unicorn mare.
Sweetie Belle's expression changed. She began to think again. It has been so long sence she lastly heard of this spell. The last time she has heard of this specific spell was like, five years ago.. when her big sister, Rarity was just showing her how to do it.
"I.. I do know one actually! My sister, Rarity, she showed me this spell before." And it was true, her big sister mainly used this spell to find gems for the dresses and clothes she was making. And now, Sweetie Belle was going to use it, for her, and her new friend's good. "I just need to remember how it goes.."

Not even a minute after that, but Sweetie's horn started to glow again, the light grew really fast, until Amethyst had to cover his eyes to not get blind. Then, her light began to fade, it began to glow like a normal candle in the night.
"Hey," Amethyst noticed. "Sweetie, you did it, i can see the gems! Haha!" He laughed happily. The silver-white unicorn gave her horn a short break and made it glow again. Then she took a quick look at Amethyst.
"I didn't notice that you're a pegasus." Yes, she sure didn't. Amethyst was infact a pegasus, a pale-purple one, with even paler markings on his chest.
"Yeahh, i am. I'm kinda surprised that you just noticed." Amethyst felt akward, then he tried to forget about that. "Now, which tunnel should we enter?"
Sweetie looked at the tunnels and the gems around them. Then she looked at the tunnels above them, they had less and less gems in them.
"Of course! C'mon, Amethyst! We're going to the tunnels above us!"
The purple pegasus felt a little un-sure for a split second, but then decided to listen to Sweetie Belle.
Both of them followed the tunnel that had less gems than the others.

After few hours of walking and walking thrue the tunnels, the two ponies felt tired.
"Sweetie Belle, remember, it was your idea to enter the tunnels with less gems in them!" Then the pegasus sat on the ground to catch a break. Sweetie Belle was frowned.
"I do remember," She turned around, facing Amethyst. "now please, get up! We seriously need to get out of here."
Amethyst knew that it was for the greater good to not make Sweetie Belle mad. He was aware of what some unicorns can do when they're angered. So he forced himself to get up, and continue on walking.

After walking, walking and even more walking, the two ponies came across thousands of iron doors, every single door was identical to the next, rusty and old looking.
Sweetie and Amethyst decided to check the doors just in case there's something, or even someone.
"Hm, there's nobody here!" Amethyst yellingly informed the silver-white mare. She, meanwhile continued looking in the other cells.
Then, she noticed an open cell. The mare looked inside. There was someone, who was just sitting there, and not moving.
"Uh, oh no.." Sweetie thought. She wasn't completely sure if the creature in the cell was friendly, alive or something else.
"HEY, Sweetie Belle!" Amethyst yelled out of nowhere. "Did you find something in there?!"
The mysterious creature in the open cell heard the pegasus's yelling and turned around. Sweetie Belle's face started sweating.
"Amethyst. Shut. Up." The purple pegasus got curious about what exactly she was talking about. Until Sweetie ran closer to Amethyst, looking at the opened cell.

The creature was already outside the cell. It started walking towards the two ponies, it's yellow eyes glowed in the dark, because it was still pretty far away from the unicron mare and pegasus colt. They, on the other hand, started walking away.
"If.. If you're trying to hurt us.. Then get away!" Sweetie Belle yelled.
Amethyst looked at the unknown creature. Then he started to recognize it's body structure from somewhere. It looked very canine-like.. just like a huge dog, a diamond dog.
Then the dog-like creature spoke.
"I... Sorry.. for scaring you guys.." That voice sounded so.. tired and.. really.. raspy. The scared ponies have never heard such a voice before. "i really didn't mean to! I promise.. It's just been like, an year sense i lastly saw a living being in here.. And.. i.. i'm speechless."
Sweetie Belle and Amethyst calmed down a little. Then the mare's horn started to glow even more, to see the dog's face better.
"Um.. What's your name, diamond dog..?" Amethyst asked nervously. The dog-stranger answered almost immediately.
"I'm Cody! It's.. it's really nice to meet you both!!" His tail started to wag happily. "You.. You guys have no idea how lonely i felt back there, in this o.. opened cell! All alone! With nobody else, but me!"
Cody then forcefully shaked hand to hoof with Sweetie and Amethyst. They both started to feel kinda uncomfortable, but they tried to hide it from Cody, to not make him uncomfortable too. Sweetie Belle smiled at the dog and asked him as politely as she could.
"Excuse me, Cody. But would you like to help me.. and my friend, Amethyst, to get out of those caves..?" Cody looked at the silver-white mare with pure confusion.
"Oh.. I've never seen the surface.." Sweetie belle looked at him, disappointed. "..but you guys have seen it! How.. how is it up there? I.. i would like to know."

Amethyst decided to tell him about the surface, Sweetie decided to clear her mind by looking better on what exactly is inside Cody's cell.
To her surprise, there was a broken chain and collar, probably Cody's. And there was stained blood on the left wall and a corpse, just sitting there. Right under the blood stain. The corpse looked alot like a griffon one. Sweetie Belle started to feel terrified. Maybe trusting Cody is a bad idea?
