A diplomacy tournament

As well as I like Illy I am more than fed up with fighting tournaments. So imagine a different tournament like this:

Mysterious cloaked structures apear all over the map to help some sinister purpose. To challenge them ancients texts must be found to prepare rituals to reveal them.

The tournament would have two stages:

I At first you would have to use your scouts to find those writings at the special buildings in your region. Temples in Larn for example. Then you would have to prepare a ritual at those places with a recept you just found(send a small amount of different ress to the place). The structures would then uncloak for three days and spies would be sent to search for clues how to destroy them. After that you send your saboteurs to level them. Later they would cloak again and you would have to visit a different special building to use another but different ritual.

II If enough structures are destroyed the cabal which placed them in first place will be revealed. As they and their slaves hide around the world they must be found be assassins to put a timely end to their actions.

Player competion evolves around the number of structures which are destroyed in the first and the number of circle members assassinated in the second part.

But if there are too many saboteurs they kill themselves and each other together with the building. If there are not enough the building is only damaged but not destroyed. So one could sabotage each other by sending more saboteurs to other buildings.
And if you send too much assassins the circle members smell the trap and flee but if there are not enough the more potent leaders might kill them first.

I think the more the merrier. A little bit of something for everyone.
