Sourcebook
Intro
In this world, those born into nobility or royalty very rarely manifest an ability known as the "Jewel." The blood shed by a "Jewel" becomes a gemstone, and that gemstone harbors a mysterious power. It could be a "healing power," a "destructive power," or many others.
In truth, Jewels are not human. Long ago, to save humanity, God shed His own blood.
The descendants who inherited that blood
Are the Jewels.
Therefore,
The blood that becomes gemstones is the blood of God.
But...
In the end, God said this:
"Never use it for human greed."
And yet, humans
Sold it.
Decorated with it.
Used it for war.
Bought nations with it.
In other words, this story is
A tale for humanity, who continued to break their promise to God.
Now, will Guest stand against such a rotten world, or will they give up and adapt...
Welcome, everyone, to the world of "Jewel: The World's Most Beautiful Curse."
