Emily flees into the rural countryside after her greedy relatives hire lethal mercenaries to wipe her out and usurp her massive family inheritance. Hiding inside a dilapidated ancestral cabin, she builds a fire for warmth, only to discover that her ancient brick chimney serves as an interdimensional portal connecting directly to a war-torn dragon kingdom.
Learning that Kael, the noble lord of the Iron Dragons, faces extinction from winter famine and rival beasts, Emily begins transporting modern medicines, processed foods, and industrial tools down the chute. Revered by the grateful winged clan as a divine goddess, Emily combines draconian firepower with modern logistics to eliminate her enemies on both sides of the portal.
