Chapter 6: OOC
The walls are 30 feet tall, the gate is an large arch that can be shut with a portcullis, so you could see through to the other side to the buildings beyond. There are buildings within 10m of the wall.
The guards seem to be interested in people and goods, they're asking questions and poking through people's stuff, if their stuff is large (ie. carts, big sacks, etc).
Jan, if you're thinking of teleporting through I'll just let you know that as it stands you cannot teleport with someone, except maybe Qwe, since you have a weight limit of yourself and 100lbs. If you put someone in the dimensional pocket there mass is still there, thus when you teleport they'll stay where they are and only you will move, essentially forcing them out of the dimensional pocket. I kind of messed up that interpretation with the Captain on the boat, but that's water under the bridge now.
