Leading a small squad of fully armed guardians, Agatha left the forward base established by the church's troops. They passed through several makeshift barricades and firing positions and crossed an intersection lit by gas lamps, eventually reaching the deepest part of a branching corridor.
The gas lamps embedded in the walls emitted a faint hissing sound. The ancient piping system provided an unstable supply of gas, causing the light to flicker dimly. Beneath this not-so-bright illumination, one could see a dark and hefty alloy door quietly standing at the end of the corridor.
The sound of a cane and heels tapping against the floor echoed hollowly in the corridor as Agatha approached the door—which, perhaps due to the passage of too much time, was actually somewhat unsealed. A narrow gap was visible between the two doors, and the lead block that was originally sealed on the bolt appeared to have sustained an undefined impact, with clear signs of stretching and tearing.
