Quote Bunyip:

a) Move my city outside the compound?

I think you can but I'm not to sure if you need at least one city at all times to be within your contour.

Quote Bunyip:

If I move/abandon the city will the fort still be mine or does it go no commander or just disappear ?

I think the fort will still be yours but I come to the same problem as above...

If the game lets you move the city without it telling you that it can't be moved, then I'm sure it will let you abandon it without any problems too.

Sorry, I'll do some digging to find out the detailed rules on building contours.

OK, so:
New contour system is implemented from scratch:

A You can now put a mark tower if:

1 Position of mark tower is not inside any contour
2 You have a city inside a contour, where you want to build a mark tower
3 You have a permission to make changes inside a contour from fort owner

B You can now build a fort following these rules:

1 Your water border is continuous and your mark tower locks it into a contour;
2 You have at least 1 normal city inside;
3 You have an ally relationship with fort’s owner, which exit is being closed by your contour, in case you connect your contour’s water with his.
4 You have an ally relationship with the owner of some contour and the permission to build on his land, inside which area you are planning to build a fort and you are using his water.
6 You have an ally relationship with the owners of all the contours blocking your way out and you are using their water.


So, I see no reason why you should need a city there after the contour is build...

Please report back on your findings.
