As previously mentioned, I have been working on a system which is the evolution of my earlier Gravity Sinister work, also informed by my experience running OD&D over the past few years. This is coming to fruition as an integrated coupling of setting and rules. I am calling the project as a whole The Final Castle, after the fortress/dungeon which is the center of the games I am running with it.
Here is the background summary, which is also the intro to the current Player’s Guide draft. This draft is actually a text-complete finished document that has already seen some play-testing but will need to see more before I decide on the best way to release it.
Scion of the immortal Basmophael, the figure known only as the Harbinger claimed to herald the next phase of reality. The Harbinger moved inexorably across the known lands, unleashing monsters previously imprisoned in the dark places of the earth, and promising great power to those that would recognize the new dominion.
The arrival of the Harbinger was always preceded by a fortress that would tear itself from the ground. Then, the legions would pour forth, destroying all defenders. If the settlement was not annihilated entirely, the leadership would be replaced with a loyal servant, and the fortress would wither, soon becoming little more than a looming husk. Then the cycle would be repeated elsewhere.
The sempiternal courts took no action, assuming that they would be able to endure any human turmoil. The agents of Basmophael, however, infiltrated their hidden strongholds. Some surrendered and were corrupted. Others fought and were reduced to shadowy echoes of their former glory. Few remain.
Using subterfuge, an alliance of champions entered the Harbinger’s castle by means now unknown. With great hubris, the Harbinger had taken insufficient precautions against such a daring attack, and was subdued, though not destroyed, as destruction was beyond mortal power. The Harbinger’s armor was found to be a locus of Basmophael’s power, though it too was impervious. Unable to destroy the panoply, pieces of the armor were divided among the champions for safekeeping, but the Harbinger’s will was underestimated. Many of the panoply bearers that escaped have since been driven mad, compelled to return with the armor to the Harbinger’s fortress. Thus, the divided panoply remains held by occupants within the castle, each scheming to acquire the entire suit, as it is said to allow full control of the castle’s terrible armaments.
Unlike previous castles, the final castle has not withered, though neither has it belched forth new armies since the armor was disassembled. Rumors say that the Harbinger’s generals and creatures have fallen to internecine struggle. The final castle broods darkly over surrounding battlefields, which seem to be slowly expanding, inch by inch, day by day, despite the absence of any true fighting since the daring infiltration that seemingly ended the Harbinger’s war.
