Game Of Thrones: Season 6 - 6 Clues From "The Door" Trailer

4. The Kings Moot

With Theon's (not particularly substantial) backing, Yara will attempt to succeed her misery of a father to rule the Iron Isles. To do so she has to convince the scruffy priest of the Drowned God that her claim is the best. Inevitably, she's going to have at least one rival, since we know Euron is skulking around somewhere.

The Salt Throne doesn't sound all that great compared to the Iron Throne, and you'd have thought the Iron Born, living on the Iron Isles might have had that name for their kingly seat...

It looks as though the Greyjoys are either mobilising their fleet or this is Euron's return, along with his own army, just in time to make his own claim?
