So there's now both anti-Stormlight and anti-Voidlight and both sides know how to make more of it. How does this influece war in the future? Fused are mortal now and so are spren. It's not so easy to apply though as one needs Raysium and there's not a lot of it. Will spren die if they are in the blade/spear-form and touch dagger with gemstone filled with anti-Stormlight?
I assume that current war will end in 10 days one way or the other, but the next one will have much higher stakes as both sides will produce futher applications of this.
Also, how did Gavilar get it? Thoughts?
