the Highlands Kingdom replied that they would of course come to the aid of their allies against aggressors, word soon began to come back that the lord of the Thunder Speakers wasn't going to help them with something they started. The Xohyssiri reported to the traders that they would send what help they could to their fellow vassals, once they had finished licking their wounds from their conquest.
So we have the Highlands Kingdom in our corner for now, and face the Thunder Speakers right now, the Xohyssiri in a turn or so, and maybe the Thunder Horse if the war stretches long enough.
Highlands Kingdom
-Lowland ally, but their goal is to conquer territory
--If we seek to just stop raids, they'll continue the war anyways
--If we try to humiliate the Thunder Speakers, they might not continue the war
--If we push the Thunder Speakers back, they'll probably stop when we stop, to consolidate their territorial gains
-With both the Thunder Speakers and the Xohyssiri on the back-foot, the war should have an initial strong start. However, if they don't wall their conquests immediately, the tide could turn if the TS and Xoh rebuild their cavalry fast enough
-However, with this war, the HK is likely to only be rivaled by the Thunder Horse as the eminent power in the lowlands, setting them up to be the empire that'll eventually roll us up
--With the blood ties to our royal family, they also have a diplomatic avenue to annex us, and convert our culture into theirs
Thunder Speakers
-Attacker from both north and east, effecting the Stallion March, Blackmouth, and Redhills
--War would be over quickest if we just seek to stop raids. All we have to do is help the HK smash face fast enough that the TS would gladly focus their efforts on defending against the HK
---Furthermore, stopping raids is less likely to develop a grudge against us, where the TS attacks us periodically with the nomads every time they're militarily strong
--Humiliating them is hard, because they're more militarily focused than we are, but the goal here is to make them develop a grudge against us
---This is the option to empower the Stallion March over time, as the nomads and Thunder Speakers give them enemies and wars that elevate the Stallion warriors' status over our other castes
--Helping the HK conquer the TS's territory puts them further on the back-foot, and the hardest to do
---Honestly, the only reason to take this option is to elevate the HK. The goal for the people for this option is to get one more province along the northern lowlands, but the HK will get the rest.
---Naturally, by empowering the HK, this is the option to prevent any diploannexation of the HK, as they'll have no reason to see us as culturally superior
Xohyssiri
-What the Fuck you gods damned disease-ridden degenerates! We gave you a the gift of life just a turn ago! And now you're allying with your ancestral enemies against us!?
-Will attack Redhills in a turn or so, with cavalry elite and proto-formation infantry
-If we just stop raids, we might even skip out on getting attacked, if their recovery stretches out long enough
As for the other options.
[] Overwhelming numbers
Human wave tactics, probably evolves Honorable Death to focus on mass death. Probably also increases the absolute number of women warriors, as focus trends towards more people regardless of sex.
[] Quality training
Focuses warriors into an elite force, reducing the size of our military. Probably gives a new Honor T1 value. Might also lead to warrior caste formation.
[] Loyalty
Focuses on bonds of brotherhood among warriors, probably, giving a new Honor T1 value. Also makes it easier for military coups to happen, as our loyalty value supersedes any questions the common soldier has.
[] Temper superstition (-5 Mysticism)
Reduces the severity of our Weapons of the Gods. Probably makes it only a chance of Stability hit.
[] Overturn superstition (-10 Mysticism, -1 Stability)
Straight up removes the superstition.
[] Evolve spiritual value (-7 Mysticism)
Empowers the benefits of our spiritual traits, most likely Honorable Death or Symphony. With these circumstances, HD turns into a purely military value, while Symphony gains a bonus towards banding together against foreigners and enemies.
[] Expand spiritual value slots (-7 Mysticism)
Straight gains another slot for a T1 spiritual value. Why would we want this right now, when we have multiple T1 values to evolve?
[] Wait
Winnow current options in exchange for more information or unique development.
For my vote
[X] [Honour] Overwhelming numbers
[X] [Mystic] Overturn superstition (-10 Mysticism, -1 Stability)
[X] [Goal] Stop raids (Easiest, annoys allies)
[X] [Stallions] Focus efforts on the Thunder Speakers
Get this war over with so we can focus on internal matters, pushing back the nomads, and keeping the lowlands political geography a chaotic mess that we can eventually dominate.
