Ajsalium is a world with a hell of a problem. Literally.
Millennia ago, a divine clash created a vortex through which an immense horde of fiends entered Ajsalium, ready to conquer it. Elves, dwarves and men allied against them, but were unable to push back the infernal tide. Dragons joined the mortals centuries later, and only thanks to them could the balance of war be reversed, and victory be claimed. But the price was high, as ever since the end of the Long War elves, dwarves and dragons are headed towards extinction.
Only men thrived, and are now the proud and undisputed masters of the world. But maybe they are too proud, and maybed there's some dispute after all. Fiends had been defeated, but not vanquished, as they retreated to the inner bowels of the world, to hell. From there they have been tempting mortals to their cause, giving them power and eventually new immortal fiendish lives. What could not be conquered by strength is now being mined through stealth and corruption.
Everyday, with each corrupted man, the time for a new war is getting closer. It's up to lonely heroes to discover the machinations of darkness and battle their minions, for the fate of the world is at stake.
