A few things.

Magic is the manipulation of creatia which is the energy from Aetherius. This is the same thing that created the Daedric Realms.

Thu'um is not Mundus bound. It is the lowest and weakest form of manipulating the orchestra of the Aurbis. It's basically a crappier version of Tonal Architecture.

My thought about Dragonrend is that it specifically targets aspects of time. Alduin is a god and it worked on him. I've got $20 that says it will work on Akatosh, Auri-El, and so on.

Peryite is (probably) not a dragon or aspect of time. He's mimicking Akatosh as he is set to take his place in the next kalpa. Daedra and Aedra switch roles every cycle.

So like I said, it targets Aka shards. That makes me wonder if it, or something similar was used to shatter Aka.
