In a world where every day could be the last and humanity was surrounded by countless monsters, the only saviors were the Phantoms.
They were humanity's only weapon capable of killing monsters and becoming stronger as a result.
That the Phantoms were the defenders of the Citadel and the creators of the future - knew everyone, without exception.
Sure, many people were living in the Citadel, millions, no... tens of millions! So, not everyone had the same good opinion of the Phantoms. But, even Proud Wing never said the Phantoms were unnecessary, let alone that they should be gotten rid of.
Everyone from the military to the common people and Proud Wing understood and recognized that without the Phantoms, the Citadel would not have existed long ago.
