The Primes live in semi-peace. Their high guard brings them happiness and relief of loneliness, and even more so do the apprentices the Primes take on.

Recently, you were taken on by (your choice) Prime to be their apprentice, and you now live in their palace. The other Primes have other apprentices---each apprentice wears a sort of garment that their Prime selects for them. For example, Nexus Prime has his apprentices wear a golden visor, Megatronus Prime has his wear a purple, gold-threaded cape sort of fabric, and Prima Prime has a similar one in white and gold over the back.

As you train in the central plaza, you see the Primes converse amongst themselves nearby. You wonder what it would be like to be one of them---and maybe you will, one day, if you can prove yourself worthy to your mentor.
