About 200 years before the events of Game of Thrones, when the Targaryens are in charge, take place in the prequel series. When the issue of who will replace King Viserys I Targaryen (Paddy Considine) on the Iron Throne arises, the House Targaryen experiences an internal struggle.
The phrase is well-known and signifies terror to readers of George R. R. Martin’s Fire & Blood novel, on which the television series is based. For those who don’t know, the two characters in the book, Blood and Cheese, exacted terrible and savage vengeance on the royal family.
There have already been gruesome and traumatic episodes of the Game of Thrones series. The third season’s “The Red Wedding” episode in particular has distinguished itself as one of the most infamous and horrifying in the franchise.
