Besides find that my ruler impregnated his 2 year old daughter?
Probably the game I'm setting up now. I let Westeros fall to White Walkers as a created-ruler Ironborn lord in Blacktyde, even though I was able to take over the Iron Islands pretty quickly and probably could have won the AI War for the Dawn if I'd jumped in when they were still in the Riverlands and the numbers weren't super lopsided. Instead I want to let Westeros turn into an ice rink and then try to reconquest it. Totally reset the continent.
Doing a bit of a eugenics project with the Ironborn in AFFC. Whitewalkers have almost all of Westeros now. 2 provinces left in the Reach, Ashkmark plus one other in the Westerlands and some of the Dayne areas of Dorne are still non-wasteland. The Iron Throne is gone. They're also approaching the Dothraki Sea in Essos. About 700,000 in wights in Westeros. 1.2 million in Essos.
I am, meanwhile, conquering just about every island I can find that doesn't connect to the main continent. I was too slow for the Arbor, Moraq or Skagos, but got Dragonstone and Driftmark away. Also have the Stepstones, all of the Summer Islands, the Basilisk Islands and am waiting for some faction strength to take over the island portion of Ib while I try to fabricate a claim on Elyria.
Right around 70k men at the moment. But what can I do with 70k men against almost 2 million wights?
I don't know. I want to try though, because I've got a god tier King right now. With the dragon he tamed (Rhaegal, who was never tamed and turned into a lunatic while hanging out on Dragonstone), he's up to 49 martial (genius, reaver/berserker, brilliant commander with some other stuff and 4 Valyrian Steel blades we got raiding Westeros as it crumbled).
My capital in Lotus Port, the Summer Palace, with huge slave camp and a monster half-brother of a martial constantly training men there has a cap of 30k+ and the upgrades aren't done.
I submit that with a dragonrider king and 49 martial, I can probably kill the wights off and win my own personal War for the Dawn that I've engineered without doing anything cheesy or use the console. Just going to run one big doomstack and use all the other men to reinforce attrition, because I expect the fights will be over almost instantaneously, even if it's a 40 or 50k wight army, but we'll see. If need be, I'll chase around the big chief Walker's army until I get him, but I'm wondering if I can just curbstomp hundreds of thousands of zombies with a guy this buff.
If the king dies before I reach my 120k army target, I'll have to wait for the grandson, who just finished his education with 28 martial already. Suffice to say, my current heir, while by most standards very decent, is going to seeing plenty of frontline duty from here on out. Kill the son off, get the grandson some +2 axes from reaving, reaver trait, berserker if lucky, inherit the swords, retame my crazy dragon and should be okay to try from the delayed start.
