The Solid Earth Kingdom has 2 Emperors.
Just like how the Skyfall Kingdom and Woods Dynasty planned to meet each other in Berlin Town, the Skadis and the Solid Earth Kingdom planned to meet in a town called Fidel.
Normally, after Amletus died, trusting the Skadi Kingdom was something difficult for the Herms and the Solid Earth Kingdom, however, Skyfall Kingdoms and the Woods Dynasty have already allied themselves.
If we add Skadi into that alliance, it would become a 3v1, which would be simply ridiculous.
The Emperors' battle wouldn't even matter because the main army of the Solid Earth Kingdom would lose within a matter of minutes.
This worried Herms, his son, Roone, however, had a different opinion in his mind.
"You are worrying too much, father. The Skadi's won't dare to betray us. Actually, Amletus's death is actually a good thing for us, we gained a loyal dog that would bite anyone we order it to without doing anything.
