Mixing Magic Systems

[Raven Wilder]

We've known for a while that it's possible to combine magic systems from different worlds, or at least to use Investiture from one world to fuel magic from another (that's how Vasher's managed to stay alive on Roshar). However, Rhythm of War is the first clearly described example of how it could be done, when we see stormlight being used to recharge the white sand of Taldain.

Given the Ghostbloods are trying to create a business based on exporting stormlight to other worlds, there must be a bunch of other ways it could be used in foreign magic systems. But how exactly do you suppose it's done?

I can picture how it might work with Nalthis's magic. You take a stormlight infused gem, then put a Breath into it like you would with any object (you won't be able to Awaken the gem, but that's not necessary). Then, when you take the Breath back, it might have become mixed with the stormlight, so now you've got an extra dose of Investiture.

The Metallic Arts are the ones where I have a hard time visualizing how they'd use foreign Investiture, since they're built around people using the Investiture inherent in their own bodies, not drawing it from an outside source.

Though, even without any of that, I suppose simply being able to export fabrials to other worlds could be big business. Even technologically advanced Scadrial would probably love to get their hands on spanreeds and painrials.

Feruchemy is, and I suppose arguably hemalurgy, but not allomancy. Allomancers basically can use metal as a conduit to access the investiture of Preservation. And since we know you can power Feruchemy with outside investiture through compounding, I'd be surprised if there wasn't a way (albeit a more complicated way) to do this with other forms of investiture.

Of all the types of Investiture we've seen, Stormlight looks to be the most versatile in terms that could potentially fuel other magic systems.  If some entity, like the Ghostbloods on purpose or Navani by accident, could find a way to unlock it from Roshar I could see it being damn near as ubiquitous as currency around the Cosmere.  Of course Roshar starts to look a lot like Arrakis (Dune) in that scenario. Harmony medallions also look like a good candidate,  although for another reason entirely.  Using one of those plugs you into the local Investiture source,  kinda like a universal power adapter.
