Another-World Game/LitRPG Tale

Sean, an overworked gamer, wakes up inside the VRMMORPG Chronicles of Atheria, not as a hero but as a lowly NPC who runs a used gear and scrap shop in the starting city. Using his knowledge of the game, he turns junk into rare treasures and quietly builds a black market empire that players and guilds alike can't ignore. As his influence spreads, Sean sets his sights on the game's main server and the powers that guard it.
