Does the void corrupt even demons like Evelynn and the kench?

Look at the Void icon we got free: the void corrups even Fidget Spinners

The Void corrupts everything in existence

The real question is does Void corrupt Kindred?

I think that is actually pretty likely. In the Kai'Sa comic,a merchant gets consumed by the void,leaving only his skeleton behind(as the void consumes organic matter,but appearantly not bones). But said skeleton did rise as a void corrupted undead afterwards.

Now the question would be how the void did that. I mean the void is likely not able to corrupt inanimate objects,otherwise we'd have hundreds of void-sandmonsters running around the desert.

This means it either corrupted what little biomass was left over,or it corrupted the spirit of the merchant that still clinged to the remains of the body.

And given that the void consumes all,I'd say that the latter option is actually more likely,which in turn means that the void would be able to corrupt spirits of the dead and likely spirits in general. And demons are nothing more than a special kind of spirit.
