What I Have Picked Up About Game of Thrones, Having Never Watched It

Because I don't live under a rock, I have not been able to avoid mentions of "Game of Thrones" even though I have never watched it and never wanted to watch it. But what with memes and 5-second clips and suchlike, I have picked up various things about it. Y'all can tell me how wrong I am, I consider this an interesting exercise.

1. It is a fantasy TV series.
2. Based on a book-series by, um, George R.R. Martin?
3. Who said he wanted to write a book series that was too violent for television.
4. It is too violent for television, but they made it anyway. It is really really violent.
5. There is a throne whose back is made of swords.
6. There is a character called Tirion Lannister who is a fan favourite.
7. He is really short, like hobbit-height.
8. He has a bit of integrity, unlike everyone else.
9. There are no good guys, it is every man, woman and child for themselves.
10. There is trial by combat (see point 4).
11. There was a "red wedding" which was a massacre (see point 4).
12. There is a blonde girl who had an incestuous relationship with her brother.
13. One of the taglines for an upcoming season was "Winter is coming."
14. Season 8 has just started.
15. It is the last season (thank goodness!).
