I'll need to have a look when I get home, but I was somehow able to clear this room of guards and escape.
EDIT: Demo uploaded. It didn't seem to record my original demo (where I had somehow maneuvered to the top-left chamber, and killed most of them from there), but this way is probably simpler.
To be honest, despite the difficulty in doing the room like this, and recognizing that it was unusually hard, I didn't think too much of it due to the author having done a number of horde rooms in this and previous holds. In hindsight, it makes sense, but I thought the in-game hint was simply a way of telling the player not to bother clearing the guard hordes outside (with the conquer tokens being unreachable, something I realized after the fact
). I didn't realize you weren't supposed to kill any guards anywhere in the area. Oh well, glad to see that hold completion wasn't impeded because of this.
