The Frost Mine's deepest veins had long been depleted decades ago, and the "blood" that the City-State relied upon for its livelihood might just be the result of some twisted affair. Deep beneath the Golden Boil mine lay a door left by the first City Hall, and today's City Hall and the Governor might also be partakers and custodians of this secret—
Even the well-trained and disciplined guardians, who often dealt with all sorts of dangerous and bizarre creatures, couldn't help but fall into silence and astonishment upon hearing this news.
In their shock, they also understood why this operation was classified as top secret and why the gatekeeper would announce the specific circumstances only after everyone had descended into the mine.
Such news, even without considering the threats brought on by the Transcendent phenomena behind it, was the plain truth of the "depletion of the mine veins" itself, which was enough to stir up a Storm in the City-State!
