Ok so it goes like this.
Long ago the two Elven kingdoms, wer once at war with one another. Both sides suffered because of it. It was a long and gruelling battle, a lot of elves suffered. Many years after the war started, a princess from the elven island kingdom, was kidnapped, word had gotten out to the other kingdom as well.
Well weeks past and the war continued to plague both kingdoms. One night the prince of the kingdom north of Stormbreakers guild, was taken as well. He awoke from his sleep to find the princess of the island, and their kidnappers.
With the combined force both the princess and prince were able to overpower them and made their escape. While they were being held, it was learned that the group that had taken them were the ones who started the war on both sides, to get the power of both heirs of the Elven Kingdoms.
Three weeks passed and both the prince and princess grew to become friends. They spent a long time making it through the war ridden kingdom of the prince. When they made it to the forest Castle, they were greeted with joy.
Though that did not stop the war from continuing. With a sad heart both heirs knew what they had to do. Going deep into their kingdoms, they took their life to save their kingdom from being over run by the group that had taken them.
In their selfless act, the powers that were once theirs grew and solidified into two crowns. Which apart were powerfull in their own regard, but if brought together held unimaginable power.
The war ended with the heirs giving their lives for their kingdoms. Many centuries later, the two crowns were brought together when King Nicolas saved and married Queen Jaileen. The crowns and it's powers seemed to merge powers and become one. The elements and powers of the wearer are amplified, and because of the selfless act of the wearers ancestors, they are protected from being controlled mind or body against their will if the powers of the crown are unleashed.
King Nicolas let the full powers out of the crown that is always with him. It may not be seen a lot of the time, but it is there. It protects the wearer from being used to by others to further violence.
Amra being the heir of the kingdom will also get some of these powers be exention, but will not receive all of them until she is crowned queen. The sword is an extension of the power of the island crown and shows that she will take over as the Queen once her parents are unable to do so.
That is all I have at the moment. I am still working on a few powers the differnt crowns have, but they all have the same basic powers of protecting the mind and body from being controlled.
