In order to find my missing sister, I sneaked into the bottom of the dark alley where the steam roared.
The "secret power" I accidentally awakened allowed me to briefly steal other people's senses, at the cost of exacerbating my thirst every time I used it.
After joining the official "Ashe Society", I discovered that my sister was actually a living sample of a forbidden experiment.
In order to cover up the scandal, senior officials smeared me as the real culprit in the serial murders.
While escaping, I found my dying sister deep in an abandoned factory - the "Ancient God Engine" on which the city depends was sleeping inside her.
If I save her, the ancient god's awakening will destroy millions of lives; if I sacrifice her, I will forever be branded a traitor and murderer.
I chose the third path: using my own blood as a sacrifice to become a new container for imprisoning the ancient god.
The price is eternal hell, but at least the city's gears can continue to turn.
