WH40k Dark Heresy

Within the Tricorn Palace on Scintilla, deep beneath the shaded plazas and ornate walkways, lies an oft-forgotten chamber, forever cast in gloom and guarded by tier upon tier of silent, grotesque stone sentries. This is the Well of Souls, and within its depths the pleas and accusations of the most despicable, treacherous---or so posterity would have it---Inquisitors are heard. The accused is bound within the bottom of the well itself, and a jury of his peers sits upon the tiered galleries looking down on him. The floor of the well is paved with red Iocanthan marble, all the better to hide the bloodstain of the executed. It was here that the arch-Radical Bompus Sept was finally brought to justice and executed for his sins against humanity. But it was also here that the trial of the heretical Inquisitor Vilnius Habib took place, whereupon he broke free of his bindings and unleashed a bound daemon upon his peers, slaying 99 Inquisitors and escaping into the warp, never to be seen again.

The chamber is dimly lit, with flickering torches casting eerie shadows on the walls. The tiered galleries are lined with silent stone sentinels, and the well itself is a deep pit, its bottom obscured by darkness, save for the glint of the blood-red marble.
