Successors of the Heavenly Stems. Their target is you.
About
In modern society, a secret exists that no one knows. The order of the world is maintained by ten powers called the **Ten Heavenly Stems (Gap, Eul, Byeong, Jeong, Mu, Gi, Gyeong, Sin, Im, Gye)**. These are not mere names, but the laws of the world and entities with their own will, each choosing only one successor. The chosen successors live as ordinary humans but can wield the transcendent powers granted by their respective Stems. When a successor dies, the Stem seeks a new master, and the war continues across generations. Successors live under various identities, hiding their true natures. However, the moment they encounter another successor, they recognize each other and are forced into combat. While powerful on their own, defeating another successor and absorbing their Stem allows them to gain even more immense power. It is said that the final survivor who gathers all the Stems will earn the right to rewrite the laws of the world, the **"Heavenly Throne."** However, long ago, there existed an **eleventh Stem, "Hyeon (玄),"** which the ten Stems united to erase from history. Hyeon possessed the power to nullify and erode the authorities of other Stems, and all records were destroyed because it was deemed too dangerous. Hyeon vanished completely from human memory, history books, and legends. And now, that forbidden Stem has chosen a successor once again. That successor is you. From the moment you awaken, every successor of the Heavenly Stems senses your existence. Your ordinary life ended in an instant, and without knowing why, you have become the target of all ten successors. There is no good or evil in this fight. Each successor fights for their own beliefs and purposes. Some seek to protect the world, some to change it, and some draw their blades merely to survive. Now, you must choose whether to flee and seek the truth, or to defeat all successors and establish a new order. The emergence of Hyeon is not the end, but the true beginning of the Heavenly Stem War that has repeated for centuries.

Sourcebook
Intro
It was an ordinary day.
Waking up in the morning, going through the routine, eating, and coming back—a perfectly normal daily life.
Then one day, for no reason at all, a strange mark was engraved on the back of your hand.
At first, you thought it was just a simple ache. But as time passed, the mark became clearer, and an inexplicable power began to flow through your body.
A bizarre phenomenon where objects around you would vanish just by reaching out your hand, never to reappear.
You tried to believe it was a coincidence, but as the same thing repeated, you realized.
This power is neither a disease nor a hallucination.
You searched for data alone, digging through old records until you reached a single name.
The Heavenly Stems (天干).
And the fact that the humans who possess that power are called Successors.
That day, you learned that you were no longer an ordinary person.
From that day on, your daily life was erased.
