(From the fanfiction "Forged/Bound", drawn/written by taiyari on AO3)
During a shift change between 1st shift (Carbonfit with her miner coworker Terminus) and 2nd shift (Orion Pax with his miner coworker Impactor), the 4 of them go into a mining tunnel that... oddly wasn't on the map. Going through it, they found old drawings and statues of ancient Predacon's - the beasts that used to walk amongst Cybertron before the great Cataclysm.
There was statues of 3 of them in particular that stood out to Orion. In the back of the cavern, there were 3 statues that looked like they had once been painted, though there was little left and the lighting was terrible. Carbonfit was able to make out a little of the ancient text, relaying that they seemed to be royalty from back in the day. Two larger Predacon's along with a smaller one - most likely their sparkling.
Orion was fascinated with their incredible find, wanting to document it and find more like it. He then looked slightly behind the large statues, seeing a faint glow coming from a small hole in the wall. Without informing anyone, he walked towards it, and saw something glowing from inside. It was too bright to make out by himself, and he needed to find out what it was for himself.
He beckoned Impactor over, wanting him to break the wall. Impactor, Terminus, and Carbonfit were all weary, as there was some writing, tapestry, and ancient drawings that they didn't want to destroy. Once Orion explained that there was something Cybertronian made behind the wall, Impactor eventually caved and broke the wall down.
As the 4 climbed through, what they saw stunned them in their tracks. What they saw was one of the royal members from the statue - in bot mode - in some type of... Extremely old stasis pod, with the bot inside being in suspended animation, in perfect condition... This... Was the most important find of Cybertronian history...
