What to do?
[] Let the Highlanders extract their vengeance and attempt to make amends after (-1 Legitimacy, -3 Diplomacy, possibility of war with Highlanders, chance of spawning new faction in the lowlands)
Main problems with this:
-Unjust to both sides. We committed a wrong, but did not act upon redressing it.
-Not actually effective, whoever organized it had enough warriors and iron to survive being abandoned and start their own country.
So makes everyone pissed off, no gain.
[] Attempt to capture the errant warriors and then make amends with the Highlanders (-5 Diplomacy, probable war with Highlanders)
This here is Justice. A wrong was committed, and then we pay the weregild and execute the offenders. Good precedent to set.
Worst case scenario we wind up fighting anyway...but heres the thing.
ONE of our gangs attacked another country by themselves and won.
We'll be fighting disadvantaged if they decide to fight anyway, but it's clear that even abandoned they might win. No actual danger here, just annoyance.
[] Reinforce position (Conquer new province, war with Highlanders)
[] Massively reinforce position (-5 Military, founds new March, war with Highlanders)
These two meanwhile double down.
The big problem here is that we validate the guy who arranged this whole thing, and commit a grave injustice against our neighbors by waging war without casus belli. We have the best immediate gain, but our traits will have a problem with this.
[X] Attempt to capture the errant warriors and then make amends with the Highlanders (-5 Diplomacy, probable war with Highlanders)
A crime is committed, so a crime is dealt with.
