A thousand years ago, the world was consumed by an apocalyptic catastrophe. A thousand feet tall Sword came from above and setttled on earth. The earth itself twisted under the weight of its power, and from the fallout emerged monstrous creatures born from radiation and chaos it brought. In the centuries that followed, humanity clawed its way back from the brink of extinction. Massive fortress cities now stand as bastions of survival, shielding the remnants of mankind from the horrors that lurk beyond their walls. Over time, a new power system emerged — one that allowed humans to awaken unique abilities at the age of sixteen. Some gained bloodline powers, inheriting ancient strengths. Others awakened elemental affinities, commanding fire, water, or lightning as extensions of their will. But when Aren Hunter faced his awakening ceremony, he awakened… nothing. No bloodline. No element. Instead, something entirely different stirred within him — a mysterious interface that called itself the Creation System. “You can create any technique you desire — as long as you have the points to pay for it.” It also granted him the ability to cultivate any technique placed within its slots. Now, armed with this strange and limitless power, Aren must forge his own path. Will he rise to protect his family and defend humanity against the darkness — or fade away as another forgotten name lost to time? --- System Interface: [Host: Aren Hunter] [Tier: Non-Awakened] [Slot 1: Inactive (0/100)] [Slot 2: Locked] [Slot 3: Locked] [Slot 4: Locked] [Slot 5: Locked] [Points: 0]

Working dead-end shifts to pay off his dead father's debts while his mother slowly dies from an illness he can't afford to treat.
