The Prophet is Aeron Damphair Greyjoy, the local religious fanatic of Great Wyk, one of the Iron Islands. This religion is all about drowning and being, if you're lucky, resuscitated. And swigging seawater out of your hip flask. I think I'll pick another religion, thanks.
Aeron learns that king Balon is dead (so we have rewound a bit) and that one of Balon's brothers Euron wants to be king. Aeron doesn't like this, and comes up with the idea to Make the Iron Islands Great Again by choosing a new king at a Kingsmoot, which is a bit like an Entmoot but hopefully doesn't take so long.
