Elegy of the Norns Heroes

Heroic Spirit, the largest city on the planet Sikoti and the capital of the ruined city-state. Light and darkness coexist in the city, creating the hustle and bustle of relic civilization. As guards of the ruined city-state, Lin Bo and Aibisi patrol at night to maintain order and security in the city. But behind the seemingly peaceful surface, there is a "black shadow" that the two of them work hard to hide. However, the peace was broken one night. The "thing that fell from the sky" fell outside the City of Heroes, and was about to destroy both light and darkness at the same time, bringing the blood-red doomsday to the blue sky. The "Norns" series of story spin-offs tells the story a hundred years ago. Behind the dark history called "Blood Red Heroes" are many unknown heroes fighting against fate with their blood.
