So I played a bit of CK2 Agot mod and played as Arstan on a whim. (No I do not have screenshots so don't ask)
It was quite fun.
So it took me a few minutes to mod the game files so that all the marriages happened like in my story.
I added a little event for The Aftermath of Summerhall, where everyone involved was all given the friend status effect, along with "Savior" with Joanna and Aerys to mirror our actions in Summerhall.
Steffon is a formidable fighter (instead of skilled he had in canon), but that's about it.
I also gave Rhaella Scholar and Erudite to add to her book-loving nature in this story, and also to up her learning because she is one of the most well-read ladies in the Seven kingdoms at this time/
During the War of Ninepenny kings war. Arstan and Jon and the Bronze Yohn commanded the main Arryn forces, while the Hunters, the Graftons, and the Waxly's commanded the reserve that are coming behind us.
We landed at Bloodstone while Ormund landed on Grey Gallows and Skull Island.
Aerys and his Massive Army landed in the Disputed lands.
so we seiged it down and all seven kingdoms slowly came to the air, until "Holy Fuck!" A Volantine Army showes up and fucks the Stormlander Army in the Ass.
Because as it turns out, Maeyles the Monsterous married the tetrarch's daughter and got an alliance with it... meaning we've got to deal with the 40k troops from the stepstones and another 45k from Volantis. Needless to say I was a little bit worried because dead old Maeyles was pretty strong now.
Then Spotted Tom dueled my ass. And this is where things get fucking crazy.
Now I'm a skilled fighter, and so is Tom, so this was going to be a hard fight... and then I killed him in a single round's worth of rolls.
The Seven were with us that day, because we just stack wiped 10 k
Now, at that moment I thought the war was going to be swinging our favor... And then Ormund's army fought against Maelys.
Unfortunately, the battle went the way of canon, with Ormund dying (presumably in the arms of Steffon) and the army getting smashed with thousands of casualties.
Then The Lord of Battles captured dad while we were made Master of Laws back home... It was quite confusing what the Ai does.
But the Ai was smart enough to make us regent and then babies! Rhaella gave birth to a little girl named "Aurelia"
As regent we decided to embezzle money to buy dads freedom... I'm sure he would understand.
Back to the war, Aerys and the Iron Throne co had some reinforcements from the Westerlands and the whole Iron fleet started raiding and sacking and murdering fools.
Quilleon turned out to be the MVP because he sacked Tyrosh, and captured three of the main enemy commanders of the band of nine.
There was one final battle against MAelys, and guess who killed him?
Ser Gerold Hightower killed him... Ironically enough but he did lose an arm.
The war was over, Maelys got executed by way of battel, and well... I continued for a few years before I decided to write the update

CK2... the only game where the stories we create are almost as batshit crazy as GRRM or my mind
