Loose Bolt

During long winters most people who live beyond the wall die. So any possible kingdoms in there would not survive very long either.

Actually it is king who decides what is legal or not and it is also he who hires HotK. So in theory it would be legal.

We know that Harry has some bastards. So if one of them is a boy and he survives long enough to grow old enough to make a claim and somehow gains enough political and military support to enforce that claim then that male bastard could inherit the Vale. But chances of that happening are very low.

Actually she will outlive all other Boltons and will inherit Dreadfort.

We know that winter is coming to Westeros. So I assume that most of elephants will be wiped out by either elements or diseases and rest of them will starve to death. After all feeding those animals would be hard even during ideal conditions and totally impossible during harsh winter.

Could Davos be agent of 7? After all he seems to have very strong plot armor.

But Gift is huge. Or land area of both gifts is about as large than average state of USA. So if a person living in there is careful he should be very unlucky if his home is visited by raiders.

It could also happen if local lord really wants to have sex with some peasant or just kill somebody. After all we know what Roose did when he saw a woman who seemed to be healthy and fertile. So sometimes people would be more safe living at Gift that near castles or manors.

Actually Roose should have had same problem bc lordlings have tendency to marry children of other lordlings. So there should have been at least some people among his followers who were ordered to kill their relatives. Or those people either disobeyed those orders or they became kinslayers.

Sansa has minor claims to North, Riverlands and Westernlands. (After all she is legal wife of Tyrion.) So if all those who have stronger claims to those kingdoms are either MIA or KIA and she somehow gains enough military support to enforce those claims Sansa could take over 3 kingdoms :lol

Ned promised to marry Ashara Dayne when he was only second son. But he broke that promise when he had very strong reason to do that. Or in my head canon Ned is much more practical and less honorable than most people think him to be.

Could Hungary produce enough black powder to keep all their firearms active without importing it or raw materials for that from other countries? After all without access to that stuff firearms would very soon become useless junk.

I assume that if mr. Martin really wants to tell whole story in (2?) more books he would have to somehow get rid of too many players and plotlines. So it is possible that Euron and (F?) Aegon will die very soon. After all if they were too successful their stories would steal time and words from other stories.

Branda Stark wed Harrold Rogers. Only reason why House Rogers even exist seems to be that GRRM wanted to honor memory of late Roger Zelazny.

Most of ex-slaves lack necessary skills to run a state. Or I am sure that very few of them know how to read and write and their other education is minimal. After all only members of elite had access to any kind of education and owned books. So if Dany wants to have working government she needs to keep those nobles who have necessary skills to run a state happy.
