Anyone confused about British politics at the moment? Here's a useful Game of Thrones analogy:
Ok, so although there are other minor houses, the main ones in Britain right now are the Lannisters and the Starks. Joffrey Lannister was on the iron throne until recently - baby faced and harmless seeming, but actually horribly ruthless and very mean, especially to the poor. But, due to his own incompetence, arrogance and stupidity, he's buggered off now and Cersei has taken over. We don't really know what she's going to do with her new power yet but, it's Cersei, so it's going to be bad.
Meanwhile in the north, The Starks have been struggling to control Winterfell for a while, partly due to not really having a very popular leader since Ned Stark died. Also. Lots of people, especially in the north of Westeros, were getting fed up of the wildlings coming from north of the wall and wanting to share their sheep and wine and whores. Even though they brought other useful things to share in return, like furry coats and fish, people were suspicious of them because King Joffrey had spent ages telling them the wildlings were to blame for everyone being so poor (so that nobody would realise it was actually because he was stealing all their money to give to his rich Lannister friends) and loads of people believed him, because they were afraid.
Amidst all the confusion at Winterfell, the High Sparrow turned up and started going on about how everyone was a sinner, and they needed to stop all the heads on spikes and whoring at once and follow the word of the seven gods instead. This annoyed a lot of the angry scared people of the north, because although religion was nice, it wasn't going to keep them in sheep and whores and it didn't really have anything to do with what they were pissed off about, but a lot of the other more spiritually-minded and less poor and angry people in Westeros really liked him, and soon he had lots and lots of follower sparrows. So, even though the Starks really didn't want him at Winterfell, and he didn't really fit in there in the snow with his sandals on, his many followers told the Starks it was tough **** and they had to have him as the new King of the North, so, they had to let him. This caused a lot of confusion because really, the High Sparrow wasn't really bothered about the wildlings, or even about Winterfell, he really just wanted to spread the word of the seven gods and being King was a great way to do that, so he went along with it. But everyone else at Winterfell was secretly fuming and were soon plotting how to get rid of him.
So basically now, Winterfell is in chaos whilst Cersei is busy plotting her next ruthless moves from the iron throne. Winterfell need to get their **** together because otherwise Cersei is going to make Westeros really really horrible, possibly worse than Joffrey, but they can't because the High Sparrow won't bugger off back to Kings Landing and the rest of Winterfell can't get their heads round all the god stuff he keeps banging on about. And, like I said, since Ned died (and, as we know, even he turned out to be a bit of a liar and a coward in the end), they don't really have anyone to challenge him that the people will kneel down for anyway. Brienne of Tarth has turned up to give it a bit of a half-hearted bash, but nobody likes her very much because she's a bit weird, and she has a history of swearing allegiances to slightly dodgy people like Jaime Lannister.
But we need them to hurry up and sort their **** out, because winter is coming. And we don't have a dwarf, or any dragons.
