While Zach was busy getting lost in his thoughts and worries, the Underworld didn't waste any time. Less than a day after the underworld energy flooded the city, forcing the alchemists to work in barracks along the road to the next city over, they already started sending underworlders onto the streets.
The underworlders were from the first and second layers, and their only apparent task was to take down the talismans inside and around the city.
The talismans weren't that much of a bother to stronger underworlders, as proven by Mursoth who walked through a tunnel packed to the brim with ones without so much as frowning. But they obstructed the flow of the underworld energy and prevented it from spreading beyond the city.
The talismans were also powerful enough to severely injure the weaker underworlders.
