After the discovery of the dinosaur bones that led up to the creation of the Dinobots and the following mayhem that came from it, the original cavern the bones were found in had been more or less forgotten. Everyone was much to busy trying to get Wheeljack and Ratchet's unruly creations to settle down or repairing the damages they had done to Teletraan-1 to spare a thought about the cavern. Everyone aside from Beachcomber, that is.
Like most of the scientists that were pacifists when they could be, Beachcomber was often forgotten in the background when the action hit. The little dune buggy didn't mind at all; it often allowed him unique opportunities like this. The chance to explore a cavern that was relatively untouched by human or mech was just too tempting to pass up. And so, with everyone's attention elsewhere, Beachcomber made his way undisturbed into the chamber.
It was extremely interesting. Mount Saint Hilary was a shining example of a stratovolcano and as such it was very unusual for it to have any sized caverns at all, much less the humongous opening that housed the dinosaur fossils. Beachcomber dug his fingers into the rough soil and was unsurprised at the readings that came back. High concentration of volcanic ash, moderate quantities of felsic rock with high levels of silicon mixed in with lower quantities of mafic and pumice. Nothing out of place.
"Well than, let's see if I can't find something out of place down tunnel number one." Beachcomber said to himself and gingerly wiped his fingers off. Humming a jaunty tune, he started his way down the right tunnel that connected to the huge cavern.
A few paces into the tunnel, the uneven floor started to gently slope downwards. The dune buggy made sure to note this odd occurrence along with the observation that the tunnel roughly remained the same size all around. Highly unusual. Another analysis of the wall farther in gave no insight into this odd phenomenon.
Half a human hour into his trek, Beachcomber came upon a very odd dead end. The tunnel abruptly cut off into a wall that appeared to have been made by something not of nature. If Beachcomber didn't know any better, he would have thought that the wall had been made by humans. But, that was impossible. The wall looked old enough to have been there for hundreds of years and if the humans had built it for whatever reason then surely they would have stumbled upon the Ark in the process.
Beachcomber brushed his fingers on the wall to see what his sensors could tell him about it before having to jump back in surprise as it suddenly collapsed. His fans sputtered to life to clear out his vents as the agitated dust filled the area. Even with the grim floating in the stagnant air obscuring his vision, he could still just make out that the path continued on past the destroyed obstacle. Carefully stepping over the rubble and moving beyond the opening, the dune buggy found himself in another chamber. It wasn't as large as the one the initially connected to the Ark but was still of an admirable size.
It also seemed to be the true dead end of the tunnel. The domed cavern had no other avenues of entrance aside from the opening Beachcomber was standing in front of, at least from what he saw. And to add another bit of oddness on top of the strange caverns and even tunneling, there were four beat up looking statues placed in each corner of the dome. Curiosity getting the better of him, Beachcomber approached the nearest statue to study it.
The statue was about a foot taller than the average human and made out of a white substance, dirty with age, and the dune buggy guessed it to be granite. It was based off of a female clad in robes and she was holding both of her arms in front of her, cupped. It gave off the impression that something was suppose to be resting in the groove but it was empty. Remembering what had happened to the wall just moments before, Beachcomber very carefully placed one of this fingers on top of the statue's head.
Nothing happened. Venting a sigh of relief, he began a basic scan of the statue to confirm his hunch on its composition when several golden lights suddenly glowed into existence all around it. Before Beachcomber could react, the lights flickered once before flying off down the tunnel he had just explored. Before the cast off glow from the gold lights dimmed out of view, several more lit around the remaining statues, each a different color. In less than an optic shutter, they were all disappearing down the tunnel at incredible speeds.
Beachcomber awkwardly stayed where he stood staring after the lights. After a moment, he hastily took his fingers back and made his way back up the passage leading to the Ark, hoping against hope that no one had noticed the odd sight. As he quickly retraced his steps, he wondered to himself what, exactly, had his curiosity gotten him into this time.
