Is the "broken hole in the wall above" the main entrance with the collapsed ramp? Or another one?
Lharzin starts speaking authoritatively, now much more knowledgeable about kingly lore and royal locks than she seemed.
"The magic inside that hole is immense, like a Godstone, which should be locked away much deeper within. It's portal magic, which we've already experienced once recently, so I will let that stand as it is. My curiosity of it is piqued."
"I recognize the key we found - it is one of the royal keys, and will open a door. We need two of them for the main entrance up there and we only have one. But just one will be enough for the secret rear doors if we are able to find them. Arnegeir, do your gods speak to inform our choice?"
