If, during the Resolve Consolidate Power Orders step of the Action Phase, there are enemy ships in the sea area connected to a port, any Consolidate Power Order assigned to the Port
is removed without effect. Otherwise, a Consolidate Power Order in a Port is resolved normally (as if it was in a land area containing no Power icons).
As far as I know this is not (yet) a feature in the online game?
If I understand well, this would mean in a 6p game that for example the port of storms end is almost useless to martell?
