What would be the powers of a Page of Breath? (Tavros's classpect)
Through most of his story, Tavros Serves himself Detachment, he fantasizes and has some pretty hard to reach ideals, and wants to fly, while Vriska insistently tries to strengthen him to reach those goals, to make him a more integral part of the plot, a Hero, she’s Serving him Breath even to the point of seriously harming the poor thing.
But by the end, when he’s had enough of Vriska’s bullshit, he Detaches himself from her group completely flipping her off, before single-handedly doing the one thing no other Ghost in the Bubbles managed to accomplish- Bring together an insane amount of Trolls as an army to defeat Lord English. He doesn’t need to Mind Control others, as a Page taking charge, people are drawn to Serve him, to follow his goals and the plot. And so she gives the Army to Meenah, serving himself Detachment, not wanting to be the leader of so many people, Vriska gets served through Tavros’ intervention, owning her in a quite cathartic moment and doing silly dances, and finally butters Meenah up to become a Cavalreaper to the ‘Empress’, effectively serving his own desires from his Childhood.
It’s also very likely if he had Ascended properly, John’s Windy Thing would pale in comparison to what Tavros could bring to the table, rather than manipulating Wind, Wind itself would serve his needs, weaponized, wielded. Which is insane to think, really- John, a Passive, Manipulation class can create a storm the size of a planet, what the hell can a Page or a Prince of Breath do with their Wind?!
