There were millions of people living in the Citadel, globally all of these people could be divided into two categories, Phantoms and Non-Phantoms.
This was much more important than a person's gender, race, occupation, age, appearance, and financial status.
Everything else depended on whether a person was a Phantom or not. Sure, there were hundreds of roles in the Citadel, as well as levels of status, influence, and income. Each had their life and tasks.
But, only Phantoms were capable of fighting monsters, and killing monsters was the only way to keep humanity alive.
The Phantoms were not weapons or robots in the literal sense of the words. They possessed superpowers, both energetic and physical, but they were still humans.
They knew how to rejoice or feel sadness, to worry or remain calm, to get angry or go into unbridled rage, and of course - Phantoms knew how to love.
