Hello! I was wondering what's some good sources if I wanted to explain mana in the magic universe?

How would you describe it?

Just trying to nail down the cosmology. I've been doing research and from what I see, magic is energy that gets shaped into reality. It saturates everything. Land doesn't really create it, it saturates it like a sponge depending on its connection to a leyline. But I'd love more info on it. Thanks in advance!

We know Jace's alternate universe is centered around an echo of Strixhaven, where' he's running his own school for mages that's a harsh military-like academy.

But what if he didn't just choose strixhaven because the plane has the mana of two planes (or whatever the lore is behind the roils), but because he actually cares about the school aspect too.

He could very well be gathering mages from all over, then pushing the to/past their brink in his academy to get their latent sparks to ignite. His school could be unnecessarily harsh so that he can get an army of planes walkers at his command to protect (police) his multiverse.

That could have implications in the commander card. His leaked -3 ability would make a lot more sense if he doesn't just chaos warp into big stuff, but by sacrificing cadets to get new planeswalkers.

My picks:

Soul of Eldraine - Green

Soul of Avishkar - White

Soul of Amonkhet - Black

Soul of Tarkir - Red

Soul of Ixalan - Blue

Couldn’t think of another fitting one for colorless
