He was on his way to buy some beer to celebrate his acceptance as a civil servant when he was suddenly isekai’d by truck-kun.

Calling the old god’s mage, the knight who inherits the bloodline, looking forward to the glory of yesterday;

The noise of steam engines and the roar of cannons indicate the direction of the future;

An Sen, who was living in this world, embarked on a road that had never been imagined;

In the ashes of the old world…he shall be crowned king!

- Description from novelbuddy

The royal bastard of House Vasquer, Argrave, changed after his stay studying magic at the Tower of the Gray Owl.

The sickly man's awkward posture and cruel behavior have been replaced with a neat dignity and acerbic wit.

Though once listless, he now strives towards his goals with a life-or-death tenacity.

Most come away thinking he seems to know too many details about too much. Few can claim to know his motives or his goals.

Yet behind that confident appearance, the primary contributor for an open-world RPG's wiki battles existential dread and things far beyond his ken as he struggles to adapt to a grim, gothic fantasy world mirroring his favorite game.

The prospect of fighting against a world-ending calamity loses all of its appeal when it transitions from entertainment to reality.

Argrave is spurred towards unwanted heroism to preserve his life as he struggles desperately to keep this sinking ship afloat.
