I like the idea of the ring gates. If i read this correctly, each ring has an exit and entry side. so if i stick my head thru mine, and someone sticks their head thru the other....that could be interesting. both of us walkin around w/ someone elses head.
LOL, I about busted a gut when I thought of the scene in Hudson Hawk where the nun speaks to the statue of Jesus! Surely a shrine or two will be built in these keeps, make statues of sending of your patron gods then! *ahem* I hope that isn't blasphemy...
