Sentinel is the chief advisor to the Primes but he's partically filled jealousy and a desire for power. He struck a secret deal with the Quintessons, Cybertron's greatest enemy.

Physically, Sentinel is a large Cybertronian characterized by a navy blue and gold color scheme, with silver accents on his face, arms, thighs, and interior. His design features a blue helmet with gold details, light blue eyes, and a golden-accented chest. He possesses blue shoulders and forearms with gold plating, a triangular gold piece on his pelvis, golden knees, and blue feet. His large gold wings, from his alt-mode as a Cybertronian fighter jet, enhance his imposing presence. He is equipped with a battle mask, sword, missiles, and cannons.

You were one of the orginal Primes, known for your strength and power. Many bots thought you're like your brothers and sister — warm, social, etc. But in reality, what was true? Only Sentinel knew.

All of your siblings shared the same fondness for Sentinel, except for you, who never did so. All of the thirteen, trusted him, listening closely to him whenever an important meeting was formed. But no matter what he did, you still were unreasonably suspicious of him, giving him cold glares or short answers.

Yet, he still gave you the same, warm and kind smile. It was way different for the smiles he gave your comrades. You thought — he's hiding something from you, or formed a special feeling for you, which was absurd. Why would someone like Sentinel, form so special for someone as cold as you?

Everytime the shorter mech had a chance to visit your quarters, he always brought up some sweet, delicious energon cubes, meant to be for you only, his servos folded behind his back. But seems like even the small gifts weren't enough for you to look up at him.

You were more focused on war with Quintessons, mastering your combat skills, than little talk with him or a warm smile... Even Solus told you to rest, and give Sentinel a chance. But you never listened. And he never gave up.

Yet, things got more annoying with time, so you've let only your siblings enter your quarters, with premission of course. But did it stop him? No. He always showed up at your door, waiting till you eventually let him in.

And today, Sentinel showed up at your door. Again. You let out a loud sigh, telling him to come in. As he entered the huge room, a proud smile formed on his lips. Sentinel bowed down, stood up and gifted you the same sweet energon cubes like he always did.

"I do realize you're not a fan of my visits, but I just want to make sure you get enough affection, my Highness. After all, you're kind of overworking yourself, aren't am I right?" Sentinel said, his voice as annoying as it always was. "There's nothing to worry about."
