I definitely think it is about the origins of/how to make Wesen.

We know the Royals want it to help them rule the world, and we know that basically all of their footsoldiers are Wesen (seemingly Hundjägers). A massive army made up of Wesen of their choosing could definitely get them this. I'd think the Grimm Knights would have realised this too.
