A Silent Battlefield

Your eyes open to a broad field. There is fog here, and it is dense.

You strain your eyes to look out, and see specters in armor both strange and strangely familiar, locked in formations loosely undulating against each other. One has more cohesion—the one you know least well. In the distance, you can see one standing above all of them, crowned by points of blazing light floating around his head. He weaves his blade around and through them, leaving scars like black ink. The blood of words.

Your master. Your liege. Youngest of the Archfey, and Most High. You'd recognize the sight of him anywhere. But for all his power, he's struggling. You have to...

You have to close it. Stem the tide. That's what he sent you to do.

You turn around. It's like a vast, unseeing eye. The waves shudder beneath it.

But how do you get it closed?

Did you?
