For Scotland Level 5+, the oceans are in play for purposes of Blight only. How does that interact with Powers, Special Rules, Events, etc. that deal with Blight?

Powers, Events, etc can add, remove, or move Blight into/out of the Ocean, or count / check it (for, e.g.: The Land Thrashes in Furious Pain). If something messing with Blight in the Ocean also does other stuff, that other stuff doesn't happen. If an Event tells you, "Do X in a land with Blight", unless X is adding more Blight, you have to choose somewhere else.
There are currently no abilities which transform Blight, but if one existed, the resulting piece would be in an illegal state and follow those rules.
