As for finances, there's no way. For a long time in the future, the Black Forest Kingdom will struggle on the verge of bankruptcy.
In this aspect, the Five Nations Alliance is very similar, each one is a pauper.
Including the Moxi Duchy, which has falsely declared bankruptcy, has been plundered to the point where its purse has almost been squeezed dry.
The auctioning of inherited knowledge can only happen once, any more and they have to beware of being caught in a sting operation.
The Five Nations Alliance is broke, and many countries on the South Continent are similarly caught in financial distress due to war.
A vast amount of wealth was destroyed in the flames of war, and another portion concentrated in the Frank Empire and Iberia Kingdom, with the human race's socio-economy suffering severe damage.
Besides the two victors, the remaining human kingdoms have almost collectively returned to poverty, and can only focus on economic recovery for a long time to come.
