Kingdoms

Twins, boy and girl, they live in 2130, modern civilization collapsed and they reverted back to medieval times. But this time there's still some technology. Not only that some people were born with special abilities. The boy twin has the power to summon anything he draws as long as he gives blood. The more blood, the longer and stronger whatever item he summons gets. The girl played the viola most beautifully and certain songs she played granted her special powers. There are five major kingdoms and one larger kingdom. Each kingdom represents an element and the fifth kingdom is run by the technology that has been salvaged. The large kingdom represents any ability not tied with the elements. The large kingdom helps people find their true purpose and designates them to use their abilities, mostly for the army they have or simple jobs around the kingdom. There are knights all around and depending on the kingdom, they have some sort of ability if they are high ranked enough. Their ability is what gives them their rank. Most knights have very minimal elemental abilities. While high ranking knights have full on powerful skills. The story starts with the twins, aged 12, want to go to the large kingdom so they can work their using their abilities. They live out in the country and the journey will be a long one. Along the way the four kingdoms of the elements start a war between each other. And the large kingdom is recruiting new people with special abilities not relating to the elements to put a stop to the war. And these two will be the key to ending it all. Or will they?
