Water Cork (water-0)
A commander may enter to attempt to remove the cork and drain the entire ocean.

It will probably take >30 strength to do it, if a commander can pull out the cork, all of the water in the ocean are drained - all water provinces connected to the province with this site, and those connected to those connected to... etc. are turned into swamp provinces.
If the commander fails, he is swallowed in the bottomless hole under the cork (=dies).


This could be quite an entertaining site (and wholly overpowered).
Can you think of a better word than Cork? It sounds really dumb.
