N is Arceus's rejected sense of apathy, incarnate as a child into the midst of the human populace, that his nature cannot be used by the likes of the Teams. However, with love blooming between Cheren and White, Bell and Black, the tenuous strings pulling him through this life are wearing thin. In little time, he will find himself stopped, his whole being succumbing to the deadening he may now recognize as his very soul - not that he is able to care. Unbound by his ignorance and unimpeded by those around him, those same surroundings will atrophy, leaving the world a lifeless husk, unswayed, from the still tall grasses to the motionless Distortion World.
All because that vivre of childhood...ended, here.
