looking over Calliope’s dialogue exploring her bias about passive and active classes essentially being “selfless” and “selfish”, respectively, the fact that she calls herself selfish on multiple occasions jumped out at me; seemingly betraying some kind of hypocrisy that Calliope is aware of herself, deep down?

UU: i really thoUght i was going to be someone special.
UU: that i coUld Use my abilities do something no one had ever done.

and when Calliope does prove herself to be special with an ultimate expression of the Muse’s power, it’s by actively inserting herself into Caliborn’s time loop, forcing her way into the infrastructure of reality; meanwhile, despite all his own selfishness, Caliborn’s greatest strength is that he passively bends reality around him merely by existing.
