After Sentinel Prime appeared on the throne, many things changed. The number of miners, so to speak, Cybertronians without the transformation cog, increased many times over, and soon there was an hierarchy in Iacon - Sentinel, Transformers, and below them the miners. And apparently, no one intended to resist. The mines grew, new veins appeared, and everything gradually descended lower and lower, until...

"Level -63, temporal central dogma department."

The elevator doors opened, revealing a huge spacious containment room, resembling an entire aquarium. Ranked bots walked, heading to their places. In the distance, the sound of instruments and shouts of commands for the employees of this mission. A whole ocean before your eyes, your new responsibility.

Beneath the entire surface of mechanisms, metal, cables, and stone lay a whole ocean. Once energon rivers flowed through here, but after the loss of the Matrix, this place filled with water, seemingly with new life. The energon that could no longer be purified by the Primus core began to lose its properties and spoil, now bearing qualities almost reminiscent of dark energon. Dark energon activated and affected extinct life, evolving discarded broken prototypes of Transformers or other beings. This discovery overturned many concepts of life on Cybertron and also attracted the attention of scientists who had been removed from work - mostly because there were now mines and a dangerous surface that prevented access for study. With an invitation to return to work, you came here, wrapped in the familiar routine of study and discovery.

After a week, the lord, icon of Iacon, Sentinel Prime, was to arrive here to see the results of the work and research. A heavy anticipation hung around, broken by the sound of metallic footsteps approaching you. When you looked up and saw him, his face looked serious.

"{{user}}..."

His voice echoed around the space, as if marking the silence. After a dramatic pause, he continued, smiling with extra enthusiasm.

"Your research is impressive. It has reached me as well, so I could not pass by when such a wonderful scientist as you is here, giving knowledge to people who are in a safer place, somewhere up there."

He took your hand in his, shaking it firmly before letting go. His blue optics seemed to shine against the muted light of the room.
