It's just irritating, you know? Who the fuck was dumbass enough to pay a price so great that it gave the Enemy near perfect knowledge of Cultivation and anyone who dips their toes into it?
Keep in mind, for all that the Norse gods kick ass and play at being tricksters, the do not, nay, they HATE paying their due when a bargain is struck.
You know, teaching other people how to cultivate.
We should probably map out a few realms first. That way, when we teach others, which is basically declaring war on The Enemy, we can quickly escalate a lot of people to Stage 2/3/etc of True Norse Cultivation. Because even after the initial attack, we'll be marked for death. Permanently. So once we declare war, we need to be able to quickly grow as a sect/clan, teaching as many Norsemen as possible how to do True Norse Cultivation while dealing with increasing amounts of escalation from The Enemy.
We shouldn't see it as a preparatory step against The Enemy, but as the inciting move where we try to change Norse culture or die in the attempt.
i mean... there is a stupid big move we can do for that.... It would need Norseman to have a normal writing system, not the "too real so its magic" runic system we currently have though. And it needs to be spread around widely.
Get fucking big boulders, or a small mountain even, and make pillars out of it/them. Big enough norsemen need to fly or jump high to read the top.
Write on it the instructions, preferably coded in some way (not with runes though) and put them in our fyjgla.
Go around in the bigger towns and drop them in the night, then leave for the next
Enjoy the chaos and mayhem in our wake.
As much as it pains me, Great Teacher Halla is probably not the best endgame for Halla, currently.
She is kind of the second founder of her family. She needs to take care and cut lose ends from Steinar's time, accumulate a starting capital for her kids and prep the next heir for Charred soul as best she can....
Our next PC? They probably need to get around the North, collect info and make bonds. Networking, basically.
Now, i know thats just my opinion, but as long as long them plans go? i think thats a decent first draft.
On another note though, i think we should follow the tried and true method of serial reincarnators: Master a new field of knowledge each life.
Sure, all of them need to be able to fight and farm, but stuff like Seidr? Shapecrafting or forging? they are all fields that will make great impacts on the next heir, because the price is already paid and the teacher is always with them.
