The Monado

Gift from the god of gods himself, these swords are the most powerful artifacts in the land and one of the main bonds to each family. While the specific powers of each sword were never revealed to the general public, it is said that the legends each family had remained the same throughout the years, as far as people could tell.

Unfortunately, the sword has one fail-safe that Ao put on it in that the sword can only be at full power when it's fully put together. Hilt to the tip of the blade. This was put in place to so that nobody could break the sword and try to spread it's power as thin as it can go to make as many godly soldiers as possible, to lessen the chance of war.
