Some time ago.
South Ridge, Nauman City.
From the southeast to the northwest, the raging winds carried the storm clouds and torrential rain along with flashes of lightning, pouring the intersecting electric light and rain curtain over the city.
Within the city, towering buildings stood tall. Spirit Energy Users' towers, Lords' castles, and the four great Alchemy Workshops each led a cluster of buildings, a so-called splendorous glow, making the whole city twinkle with flowing light.
The shadow of the Bison Mountain Range faintly emerged as thunder struck, while nearly all the lightning converged on the lightning rods of the city's Alchemy Workshops. The dense, surging current, carrying heat enough to melt metal, was tamed by the fluttering Inscriptions, gathered into the Furnace Core, and transformed into mild electricity, becoming a resource that could be utilized by the masses.
