Guardian Shadows

They are like a suppression system that prevents the Dragon Demon King worshippers from operating out in the open.

The Guardian Shadows exist to stop the prophecy told by the Dragon Demon King worshipers.

There had been souls of the dead where the enmity against the Dragon Demon King worshippers couldn’t be washed away. The souls was confronted with the essence of this magic, and they were given a choice. They could either pass on to the land of the dead or they could give up the peace of the afterlife. They could become a part of the magic, and they could fight against the Dragon Demon King worshippers until the end of the world.

The Guardian Shadows were the souls, who picked the latter choice.

They was founded by Carlos.

There are few Keepers of Prophecy among them, When they became Keepers of Prophecy, they no longer aged, and they only died when they were murdered. They had been in a constant state.

When they suffered their first death, they were able to become a part of the Guardian Shadows. It was a great magic that changed the order of the world.

The Keepers of Prophecy are Azell descendants.

Moreover, Carlos had used the fact that they were of Azell’s bloodline to safekeep his Dragon weapons.

This was why their lives ended when they transferred the Dragon weapons to Azell.
