None know from where the Heresiarch first came, but all remember the night that it did. It rode down from the bleeding stars on a great serpent, hurling bolts of obsidian lightning that shattered the monuments and capitols of every nation. Its infernal army swept aside the defenses of the mortal empires in a single hour, decimating legions once thought to be the invincible fist of humanity's god-kings. Faceless priests - each bearing the symbol of the trident - drifted through the fallen cities and scorched villages on a frigid wind, and when they rose to greet the huddled men and women ringed by their festering, bloated dead, they spoke a single, simple offer: worship the Heresiarch or die. Thousands of crusaders fell tonight so that you might be given this chance. In a last stand that, for the first time, united all of the empires of humanity as brothers and sisters, a way was cleared into an infernal stronghold said to contain a gate to the Heresiarch’s fane. All is silent save for the clangor of distant battle. Surrounded by grim-faced knights and teary-eyed peasants – their hands clasped in desperate hope – you step through the glowing, churning doorway, knowing there will be no help and likely no return.

In what became known as the Age of Madness, an astral lich calling himself the Crimson Hand descended from the sea of stars, setting his fell gaze upon Gaea. Her red moon he made both his temple and his phylactery, and from there he sought to enslave those who would be ruled and devour those who would not. The Ancients of the four corners of Gaea united their knowledge against this threat, constructing a colossal golem, and inscribing the four POWER WORDS upon four scrolls. These scrolls they fed to the colossus, who ascended to the crimson moon in an instant. The sages of the realm watched as the flashes of battle signaled in the night sky, ending as the crimson moon itself split in half. The lich and the colossus were destroyed, and the Age of Madness was ended. Millennia have passed, and now a new threat rises from the netherworld. The four POWER WORDS have been forgotten, lost among the shattered remnants of the moon. The sages have once again united what remains of their power, this time to teleport a paltry handful of crusaders to retrieve the lost scrolls before the world is doomed.
