Solterra has no power at all. The most he has is 1,000 troops and 5,000 domestic peoples that are almost guaranteed to follow him no matter what. The rest of his "Kingdom" is comprised of Lundland people. And to them, Solterra is just some village boy from the Ordained Kingdom that inherited riches from an old fart and was given Lordship because of it. Solterra is nothing compared to even the lowliest Lord that actually has a real reason for Lordship.
Ask Flooby, Solterra only has his word. Throughout the entire roleplay he was struggling to keep power as he had no reason to even be a Lord in Lundland so it was not only other Lords/Ladies that disliked him. It was through morale alone he had caused the people in his Kingdom to calm down and for his troops to die alongside him no matter what. Every battle Solterra went against he didn't get the bad side, he promised the safety of everyone in his Kingdom because that's all he could give. It was because the fact they started to see the truth in Solterra that soldiers were about to raise from peasants without force or draft. Solterra gained so much money from the pillaging of the churches which he used to feed people and rebuild the churches. He gained extreme amounts of food from taking the Fortress of Trisch. He became rich and gave everyone a little something before the war started simply because he thought they deserved better.
At ANY time, they could have ALL deserted, but because of his words and his promises, they all stayed by his side. Ask Flooby, please do, I've said it so many times. Solterra was struggling to keep control and power, and he nearly lost his capital. But even Flooby said I practically didn't have to ask, anyone from any fief was ready and willing to grab a sword and fight by Solterra.
It's one reason why Solterra was going to leave.
Ask Flooby, ask him
