Mariela, an alchemist who produces life-giving drops essential for creating potions, resides in a quaint cottage situated between Citadel City and the perilous Fell Forest. Her routine of crafting and vending potions is disrupted when a cataclysmic event—a monster stampede—ravages Citadel City and the Kingdom of Endalsia. Fearing for her safety, Mariela freezes herself in time in a misjudged attempt to seek refuge, only to awaken two centuries later in a world where alchemists are scarce. Encountered by the Black Iron Freight Corps, she is ushered to Labyrinth City, the former Citadel City now in disarray due to the absence of new pact bearers. Mariela's arrival heralds a glimmer of hope, as her cheerful demeanor and alchemical expertise breathe life into the desolate city. As she navigates this unfamiliar landscape, Mariela grapples with the loss of her former unassuming life, embarking on a journey to revitalize Labyrinth City with her unmatched talents.
