He waits for you

"Alright then, so the wolves take the key. One of them stays with me then," I affirm with a bitter smile, my stomach rolling with the thought of what is to come. I don't exactly relish the idea of bedding Azrael and running from him straight after, but I suppose if this is our last hope for escape, then it must be done.

Ingrid nods once.

"Once you have it, all you need to do is fit it into the gateway at the end of the hollow woods. Unfortunately, this is quite the task as the entirety of the wall is enchanted to look like one big mirror coating. However, I happened to know the location of the keyhole, and will be awaiting you there. Fortunately after you find me, it should be all smooth sailing. It is magically enchanted, so the key should slot right in. We will be waiting for you there, just make sure to hurry."
