[X][React] Reach out to the Zaradysh and Boarfolk nomads.
I think encouraging revolt is far too risky as of now. If the revolters do win, then we get the Caradysh crushed and an ally among the Forluc, sure. If they lose though, Urth will be legitimized, the Caradysh will have replenished their army with wights, and this could all be blamed on us. It's far too risky for me personally.
Instead, I would advocate creating allies among those who remain that aren't the Forluc/Caradysh. Heavy Cav would absolutely dominate the Forluc in the lowlands plains, and doing this would leave Urth without the boost to legitimacy they would get otherwise if the revolt failed.
