Heavenly Sword Lore - The Legend & Guardians of the Sword

The animated lore of Heavenly Sword acts as a prequel to the events of the game.
Heavenly Sword is an action-adventure hack and slash video game developed by Ninja Theory for the PlayStation 3 console and published by Sony Computer Entertainment Europe. The game was released in 2007.
The game's story and mythos revolves around the titular Heavenly Sword, a blade said to have been wielded by an unnamed Heavenly deity against a demonic warlord called the Raven Lord. After the battle was won and the Raven Lord defeated, the sword was left in the mortal world, becoming the center of wars over its power. The fighting made the sword lust after the life of its users, eventually killing them after a short time. A warrior tribe finally took charge of the sword, ending the wars and pledging to keep it safe and unused for the world's own good. Among the tribe, a legend said that the sword's original wielder would be reborn in the year of the "fire-horse", and that this figure would unite the world's scattered tribes and lead the world to peace.
