Arthur was a boy without power—one who could never shield those he loved, a truth written in blood when his parents sacrificed themselves defending him during a devastating Gate outbreak. As sole survivor, Arthur endured weeks consumed by despair, believing his existence had ended. The unbearable pain in his chest seemed proof that corruption was spreading through him, a final curse from the void creature responsible for his family's destruction. Instead of death, something miraculous occurred: his Realm Core began to form. Two months later, he would be thrust into the next realm, where dormant abilities would surge through him, transforming him into one of the world's legendary "Chosen"—elite warriors designated to shield humanity from Gate catastrophes. Now Arthur ascends through the seven realms, seeking power to save his world. But salvation may exact a price far darker than he ever imagined.
