As Alph Ascends, he feels his mind expand, the rush of Artisty- of Virtuosity plunging his mind into the tides of glory. He feels himself stretch towards the heavens, his body being annihilated as power binds him, as a conduit, as a Vessel.
Time slows as his awareness grows. There's so much more to the world than he ever could have thought! Axi with bizarre properties, Colors that mortals can't see, and a scope to the cosmere- it's smaller than he expected. And along with that understanding comes power. So much power. Alph knows he could destroy the cosmere. He won't, of course. Not yet, at least. He pauses for a second, peering inward at the spiraling infinity. During his ascension, he appears to have transitioned to the spiritual realm, where time and space merge into a single point. He can read the future here, at least the possibilities of one.
Go. Create. Command Splendor. His power demands. Who is he to deny it?
And so he spins off, searching for a blue giant star, preferably in a system without any terrestrial planets.
In the spiritual realm, the God of Art smiles. If those who knew him best could see it, they'd be worried.
