The legend of Zias

It all started some centuries ago, when the four kingdoms started a war against each other. King Perdiccas of the East didn't agree with Queen Elena of the West and King Karl of the South didn't like King Perdiccas' way of ruling the east. We also have the great kingdom of the North. It used to be so glorious but now it's like it's almost frozen. Queen Sofia was a great ruler; she went into the war to stop the war. She wanted to save lives.
Now they all are dead, now their grandchildren are ruling and soon their heirs- their children will be ruling. But no one knows where the crown prince of the North is. No one knows anything about the north these days, we only know about the past. Like I said it's like the north became frozen when Queen Sofia entered the war. We all heard small stuff but that was pretty much it. We heard rumors but no one knew if they were true. No one has ever met someone from the North these days. No one knows if the North even exists anymore. What happened to the great kingdom? Why did it fall? No one seems to have words to describe what happened because no one knows. But people are saying that Zias- the crown prince of the north, King Asen of the north's son has ran away and he never was found. He apparently ran away 8 years ago and for the last 3 years he had been assumed dead. We know much more about The west, the east and the south. The ruler of The west is King Mikael but soon Crown princess Avery of the west. At the East we have Queen Mona but soon crown prince Aleksandar. We also have the kingdom of the south where Queen Isabella is ruling her daughter the crown princess of the south is Julia.
