Suppose you live in Westeros and you want to visit your neighbors. Great! But your neighbor also lives in Westeros, and Westerosi folks can get a little stabby. Yet, it's important that you and your neighbor have a peaceful conversation about uhhh crops or the state of the Realm or whatever bullshit without losing an appendage. Luckily for you, Westeros has a plan for that called "Guest Right". This practice of allowing guests safe conduct while under a host’s roof in exchange for a cessation of hostilities, is an entirely contractual relationship. One person gives something to another, and that person gives something right back. Like other contracts, there are certain formalities that must be observed for the contract to be properly binding.
In the show universe of Game Of Thrones, the question of whether it is possible for a woman to sit on the Iron Throne is well-settled. Cersei Lannister, First of Her Name, Queen of the Andals and the First Men, and Protector of the Realm, has sat the Iron Throne for almost 3 years of real-world time since King Tommen’s abdication. While plenty of Queen Cersei’s subjects are a little miffed about that, the realities of who currently wields power in Westeros make it possible, if not overwhelmingly likely, that Cersei’s successor will also be female. Thus, we can fairly say that in the show universe the (dragon?)glass ceiling has been thoroughly shattered. But what of the book universe of A Song of Ice and Fire? Is it legal for one of these capable rulers to declare #ForTheThrone in Book Westeros? Most Westerosi believe it is illegal for a woman to rule. They are wrong. (cont)
