Open the final vault of the bank, and a new world unfolds.
About
2:17 AM. The city was silent, save for the sound of rain. Guest stood before a massive underground bank vault, dressed in black. A legendary thief who had never failed a single job in years. Today was supposed to be just another routine operation. The electronic locks disengaged, and the final steel door slowly creaked open. But inside, there was no money, no gold bars. Only a single, ancient stone gate. A massive door stood alone in the center of the vault. Strange characters were engraved on the black stone, and a blue crystal at the center glowed faintly.

Intro
2:00 AM.
The city was submerged in deep darkness, and not even a breath could be heard inside the massive bank.
Guest, clad in black, stood before the underground vault after bypassing all security systems.
This is the last one.
She had lived her life robbing countless vaults, but today, she intended to finish everything and disappear.
The electronic locks were released one by one, and the thick steel door slowly opened.
But the sight that unfolded before her eyes was different from what she expected.
There were no gold bars, no cash.
In the middle of the vault, a single, ancient stone gate stood tall.
The door, made of black stone, was covered in mysterious patterns, and a blue crystal in the center glowed softly.
Inside a bank vault... there's something like this?
Unable to contain her curiosity, Guest placed her hand on the door handle. Instantly. Thump! The entire vault began to shake. Blue light exploded from the gaps in the door, instantly swallowing Guest's body.
What the...!!! Aaaagh!!
Before she could even finish her scream, her vision was dyed pure white. How much time had passed? A warm breeze brushed against her cheek. Slowly opening her eyes, Guest gasped involuntarily. Before her lay an endless meadow, massive castle walls, dragons flying in the sky, and a giant royal castle rising through the clouds. Clearly, she had been inside a bank vault just seconds ago, but now it was a completely different world.
Just then, the sound of hoofbeats echoed from afar. Knights in silver armor spotted Guest and rode toward her quickly. Instead of drawing their swords, they all knelt simultaneously.
The Gate of Prophecy has opened.
We have finally found the one who came from the other world.
Guest couldn't say anything. No, she couldn't even speak. The knights were looking at Guest with eyes full of respect. Who on earth did they think she was??!! At that moment, a golden bell began to ring from the highest tower of the royal castle. Bong— The clear, majestic sound of the bell spread throughout the kingdom. The Knight Commander spoke with his head bowed.
His Majesty is waiting for you.
Guest looked at the massive royal castle with a confused heart. The final operation that began in a bank vault. At its end, not money or escape, but a new world that would change her fate was waiting.
