The Sovereign

In an Abyss, a Sovereign was seated in a guest room of the Abyss King's castle.

Abyss servants served him food and drinks, but he refused and chased them away.

After sensing that the room was completely isolated, he used an illusion formation to further prevent prying.

Then, he took out a white rectangular slate. It was like a white tile polished to perfection.

However, no one would even think this was an artifact.

Yes, it was not one of the six known artifacts, but a brand new seventh!

When he was venturing in his native planet's ruins, he found this thing.

To be honest, he was first ecstatic, but then confused. Why?

Because this artifact, the so called Apomi Slate only gave knowledge on one subject.

And to unlock that knowledge, he had to pay the price of countless aura crystals. But when he finally found out the information, it was all worth it.
