In Flannel Province, within the sewers of Frostwind Territory, lay a solitary mirror.
It looked like a makeup mirror used by a noblewoman.
The design was similar to a hand fan... Its lower end was a slender wooden handle, far cleaner than the part near the mirror's surface. It seemed it was originally meant to be inserted into something but was taken out on its own.
But if someone were to come here, they would probably notice something out of place immediately.
——Because in these filthy sewers, the mirror alone was spotlessly clean.
Without warning, light burst forth from the surface of the mirror.
Like a curled fishing net slowly extending from underneath the water.
Brilliant golden interwoven light erupted from the mirror, casting upwards onto the ritual array that had long been carved above.
