We started our first game of MoD expansion. And we faced a problem when we resolve the Westeros IV Deck.

Scattering Dissent
In reverse turn order, each player moves a loyalty token to an adjacent area (if able). The Targaryen player may cancel each movement as it happens by discarding 1 power token.

So could a player move the loyalty token from a land area to a sea area?

It isn't explicitly stated anywhere in the rules, but I'm pretty sure you can't. There aren't any houses to support house Targaryen in the sea, so it would be pretty silly to gather support from the sea.

I think, that you can only place loyality tokens on land areas, correct me if im wrong!
