Ok, you have imagination, you could just start writing fairy tales
Just I can't understand how a tunnel is spotted when you're inside closed walls and want to use it, but you are not when your enemy's army has routed you and is chasing you a couple of steps behind ^^
And well your tunnels aren't large enough for people bringing food but for just for /a bunch of tartarians lead by a two headed Wyrm/? Mmh.
