Discussion and speculation stuff:
Frigga/Texulchimum seems unlikely to advance a marriage proposal that is plainly illegal – only her necromancy will not be evident – and Anders is not hiding his training, so yes priests can marry. No Imperial in the story so far has had a harem – all men with multiple marriages have been made sequentially following the former wife's death.
Yeah my guess is that the marriage laws are monogamy oriented. But at the same time it might be fine to have an unmarried partner since Phillip is openly a bastard. Maybe as hereditary dictator Arawn could just change the laws for poly.
If we are going to abandon the last year of training with the matriarch we should take the hex.
An underground network that we could work with is invaluable. Even if we don't have control over the network, it just being friendly to us could really help with spy craft.
That's what I'm now hoping for from the hex deal. Hopefully we luck out and get some allies skilled in tradecraft to defend against the assassination plots. Maybe whoever killed Vera is the brother who would inherit New Mahallo if Arawn and Pennete die.
The crusade resolving as solidly as it did in what has turned out to be Felix's favor (what a chad) changes things IMMENSELY. It means, in my opinion, that focusing on traditional allies (except Penteram) and resources as our main insurances for power is going to be a bust - the Imperials have been sort of taken out of play for now. Instead, I would like for us to go full fucking bore into maximizing the strength of our bonds, alliances from the Court of the Lich and our magical power. We are NOT going to out-economy and sure as FUCK NOT going to out-military Gigachad Ass-Beater Prince Felix, but we can probably out-magic sideswipe him.
Accordingly:
Do you take Matriarch Mire's offer?
YES. Taking the vampires an alliance would be a damn nice asset for the sorts of espionage and intrigue that I think is our smartest route forwards for our sibling rivalry, AND it's probably the single best route currently at this moment visible to us that we have of any sort of continuation between our learning of magic in the Lich's Court and back home. WE WANT TO GET REALLY GOOD WITH MAGIC. WE WANT TO GET REALLY REALLY GOOD WITH MAGIC IF WE WANT TO COMPETE WITH THE BIG-BALLER NO-BALLER LEAGUE. YES.
I suppose magic could be the path forward. But I'm not certain yet. I feel like there's not enough information on the Volcanique Confederation, but that's not a bad guess though.
You also learn from the letter that some top secret negotiations are in place with the orc blooded people of the Bloodstone Plateau. Your brother is not privy to these discussions, but he speculates Penteram plans to pay them off to abstain from conducting raids should the Titan Pact get involved in the crusade. Andre writes that the leadership of the fortress is particularly cruel; They took many female captives during their great raid, violated them, and allowed them to return home with mixed-blooded children with the express intent of dividing families and communities over if said children should be allowed to live and how they should be treated. Fathers and husbands killing daughters and wives over the shame has become distressingly common.
It's good to know that the Bloodstone Plateau is willing to accept tribute. Cools the situation down a bit from ongoing threat to looming danger.
This world is brutal. They have war crimes are occurring just like in real life.
