What if LE and Calliope were swapped with Caliborn being a female Muse of Time and Calliope being a male Lord of Space?

Well that depends heavily- Was the gender switch just because of the Classes, which is not necessary if that’s the case, or to make Calliope the bad, Chaotic one, as we know the way Cherubs pass who’s good and who’s bad is through who wins in the mating process?

If Calliope is the Asshole as a male Lord of Space, I could see, rather than the Timeline falling in place to make everything follow Caliborn’s rule, it would be the First Guardians and SBURB itself, Space, that would favor the Lord, with Time, then, becoming a well of limitless possibility not bound to an Alpha, but with a possible Alpha ‘guide’ of the best way things can go, guided by the Muse of Time’s influence.

If you mean, however, just the Lord of Space being Good and the Muse of Time being evil, however, the bad Muse of Time might have a skewed vision of reality, something like, Life is Suffering, everything Comes to an End, so let’s End Everything and liberate everyone from their Pain. Commanding the Timeline down a specific path, severing Doomed Timelines, bent on Oblivion not for the sake of Selfish Destruction, but a really fucking messed up vision of reality. Meanwhile, a Good Lord of Space would be in direct Control of the Setting of the story, of the First Guardians, leading the Reality in an attempt to counter the Evil Muse’s path of destruction, maybe even directly influencing the Creation of the Universe to try and escape this Alpha Timeline.

It’d honestly be a pretty interesting shift in the story.
