[@MrDidact] Also, some food for thought, is to have House Rykker helping the Stepstone rebels, by allowing them safe harbor to make their little visit to you. I would assume you would have it so no unregistered vessels would be able to make port at King's Landing, and I'd assume that the Stepstoners themselves would want to get through customs unchecked, which could give precedence to the idea of having inside help. A severed head isn't exactly something you carry about freely. But anyhow, my brain must divert to writing my post, I've been procrastinating.
