Elevator Shaman. The Marshal of Magic Series

ELEVATOR SHAMAN This building wasn't zoned for the dead... but someone forgot to tell the tenants. Luis Mendez is just a graveyard-shift janitor trying to make rent, mopping floors in the sleek, soulless Vespera Tower. But when the elevator starts stopping at unlisted floors - shadowy realms like "Sub-Basement 3" and "Mezzanine 7" - his mundane life takes a sharp detour into the supernatural. A half-melted keycard opens a door to a 1920s office frozen in time, and its ghostly secretary, Nellie, delivers a chilling warning: the "higher-ups" are closing the in-between floors. What starts as a curiosity about phantom floors quickly spirals into a desperate fight for survival.
Luis discovers Vespera Tower isn't just steel and glass; it's a "soft spot" between worlds, a vertical village teeming with exiled spirits, from dead office workers sipping eternal coffee in "The Break Room" to ancient entities guarding libraries of burned contracts. But the tower's enigmatic CEO, Silas Vell, isn't just renovating - he's exorcising. And Silas is far more than a ruthless businessman; he's a Leaseholder Demon, feeding on trapped souls to fuel his corporate empire.
Now, he plans a mass eviction spell to sell the tower's "dimensional weight" to something far worse. To save these spectral squatters and prevent an apocalyptic catastrophe, Luis, the most unlikely of heroes, must: Team up with Nellie, the resourceful ghostly secretary. Ally with Darnell, a grizzled ex-security guard turned elevator mechanic who knows the tower's secret passages and blind spots. Navigate nightmarish pocket realms like the "Shadow Lobby, " where the artwork screams and the inhabitants are faceless.
