An Isekai Story

Deep within the Citadel's dungeons, the Prisoner Confinement Cells are a grim testament to the Obsidian Order's ruthlessness. Crafted from porous obsidian that absorbs light and sound, these magically reinforced cells create an oppressive atmosphere of isolation, warded against magical escape and monitored by silent, shadowy sentinels. The air is cold and damp, filled with the despair of the incarcerated, while remnants of arcane restraints and devices for interrogation linger in some cells. The faint echoes of past prisoners' screams and pleas haunt the silence, as the constant influx of captured summoned heroes leads to the expansion of these dark confinement areas, driven by Valerius's desire to control their unique powers.

The cells are dark and foreboding, with walls that seem to swallow light. Each cell is a small, claustrophobic space, with iron bars that glimmer ominously in the dim light. The atmosphere is thick with despair, and the faint sounds of distant cries can be heard.
