Some suggestions

5. Considering that Aegon was advised the following wrt the Iron Isles:
    - Burn them and everyone on them with dragonflame and start again on the ashes
    - Give them to the Lannisters
    - Give them to the Starks
    - Give them to the Tullys
If I was Vickon Greyjoys whilst technically the Kingsmoot had chosen me I would nevertheless be enormously grateful to Aegon for a. not barbecuing me, b. not making me a vassal of some greenlander, c. be grateful for giving me the opportunity to persuade the other lords of the Isles to choose me to rule them. Essentially Aegon did grant Vickon a kingdom through the means of a kingsmoot and promising to accept the choice of the kingsmoot

6. I'm repasting this from another thread but basically there is a misunderstanding between what is a junior branch of a house and cadet house going on here. To explain:

For game purposes a cadet house and a junior branches are different things. A junior branch is a branch of a house that hold lands but is not the head of the house. The cadet house is when a branch drifts so far away from the main branch it acquires a new identity of its own.



To use a ASOIAF example House Karatark is a cadet house which was originally a junior branch of house Stark. When Karlon Stark was given lands his surname was Stark and his children's surname was Stark from the junior branch of the House, the Starks of Karlon's hold. As time passed the identity of the Karhold Starks diverged from the main branch to the extent that they acquired a new identity and became Karstarks. This is a contrast to say the Targaryens of Summerhall, when Maekar was given Summerhall he established a junior branch of House Targaryen with Daeron the Drunkard as his heir, with Baelor to inherit the throne, but his surname remained Targaryen, it was a junior branch and if those higher up the succession not died the branch would remain a separate branch from the main one. Now perhaps over time the Summerhall Targaryens would have become Summergaryens or something but it would have required a large amount of time to obtain a unique and distinct identity. To now turn to an example from real life, in the British royal family Prince William is the Duke of Cambridge and he and his family are referred to as the Cambridges, Prince Harry is the Duke of Sussex and his family is referred to as the Sussexs, and assuming nothing happens to William and his children Harry's family will be a junior branch of the house of Windsor, but no one would think of it as a cadet house currently, meanwhile the family of the Dukes of Kent, the Queen's cousins could easily be described as a cadet branch as it's fairly far removed from the main line and has a unique identity. In time the Sussexs will be a cadet branch but probably not until Harry's grandkids hold the title, right now their identity is a junior part of the main line.



Now bastards is where things change. Bastards cannot inherit their father's name. This is why Ramsay was not Ramsay Bolton until he was legitimised. If he was granted lands but not legitimised he could not legally call himself Ramsay Bolton, his options would be Snow or some new name of his own devising. Hence the option to grant a cadet house to bastards exists as if they are unlegitimised they would just get a random autogen house. Now I'm all for a mechanic where if a junior branch has a title of their own for say 4 generations they have the option to assert their unique identity and found a cadet house, but if say Garlan gets his hands on Brightwater Keep his surname will not suddenly stop being Tyrell.



I think a further complication to the discussion of cadet houses comes about from heraldry, and the assumption that a different sigil means a cadet house. This is not correct. GRRM is a big fan of heraldic designs and embraces the concept (far from universally applied in medieval heraldry) that no two individuals can't bear the same arms at any one time, a concept that requires offspring to differentiate their arms from those of their fathers and siblings. This is why ever Targaryens entered into the lists at the Tourney at Ashford meadow has their own unique sigil, this is not to say that they are all cadet houses, especially considering that one of the people with a differences sigil is the firstborn son to the heir to the throne. If one of them became head of the house they would then default to the traditional arms.

7. I fully agree with this - although I think it could just be for if Dorne is sworn to the IT in general so the Martells could be given it? It wouldn't surprise me if part of the deal in the annexation is the Martells getting a wardenship, seeing as if they didn't they are part of the Wardenship of the South which is held by the old enemies from House Tyrell
10. Yep fully agree with this, or if they must loose their dynasty let them still be listed on their family tree, given all the High Septons we know to have been Hightowers etc, also maesters and normal septons also give up their surnames (Septon Sefton in Sworn Sword tells us this) but they don't currently loose their dynasty, I think the High Septon loosing their first name is an adequate representation of them publicly renouncing their earthly name

4. I think has legs, I'd also add the ability to have knighthoods and tourneys and supersede the "The Seven Doctrine" for the Ironborn entirely as if you had the doctrine you propose you've got most of the features already, and it reflects that the Drowned God and the Seven have a longer history of relations and would therefore syncretise far better than if the Ibbenese say were to suddenly incorporate ideas of the Seven into their faith lol
