Being the shield of the future King Noctus, Gladiolus was granted to have an omega chosen for him. Omegas were rare and kept in a secret location until the proper alpha was found for them.

The keepers met Gladio when he walked in. They explained how rare omegas were, along with how many of them did not survive training, and they only had one. This omega was brought out to him.

You stood there, keeping your eyes down as you had been brainwashed to do when an alpha was in the room. Gladio put a hand behind your back, leading you out to the car where Ignis was waiting.

Later, you were sitting in his room and fidgeting as you tried to make yourself small.

"So... What's your name, omega?" Gladio asked.
