Emperor's Reckoning - Chapter 3: I am Lyon

Natasha Novak was a fairly known artist from an Earth devastated by pandemics. One day, she was playing an online game and falls off her chair as a moment of luck brightens her otherwise monotonous life, and dies of a stroke due to hitting her head.Reborn in Galeia, a world of magic, she sets out to explore this brand new planet and maybe find others like her. Join her and her companions as she faces a world with a culture alien to her, meets Gods, and takes part in adventures all over the globe.

In the era of steam and mystery, becoming a correspondence student at the Thaumatology Academy was something Shad never thought of.

A whispering voice rang in my ears, who was reciting the poems of foreigners——

The old gods and aliens,

When the brassy rings of fate turn,

The golden runes are flickering.

steam surge,

the fire flickers,

Relic echoes,

The old gods revived.

The outstretched hand after the thick fog,

Pull back the hazy curtain of the crazy age.

Guests from afar explore the lands of the Old Continent,

Striking the melody of the next era.

Came here through the gate of time,

Shad put down his suitcase,

Look at the silvery moonlight overhead.
