In Act 1: The Sleeper Rising, you and your fellow heroes are caught between the religious police and a cabal of hidden cultists. Recruited by the king of Axphain, you must begin to root out the cultists. You discover a network of tunnels converging on the Royal Place, which leads to high-stakes intrigue and investigation.
At the King’s masquerade ball, an eldritch horror is unleashed, and the ultimate abomination rises above the city! Yet, this is only the beginning – volume 1 of The Big Sleep – an entire campaign devoted to exploring the terrors and wonders of the Great Old One Tsathoggua – the Sleeper.
In Act 2: The Doomed World, you and your allies have temporarily escaped some of the worst effects of Tsathoggua’s rising, but now the Great Old One walks the surface world. What do the Sleeper’s demented cultists seek? You follow a pilgrimage of cultists through a deadly forest, to an enchanted mountain, hollow within. From there you must penetrate and escape a fortress of sub-human bestial horrors.
Eventually your heroes enter the neighboring, not-yet-blighted Kingdom of Yetive. You rush to seek the Queen’s aid, but she has her own plans and goals, and you and your fellow heroes are not the only factions calling upon her.
In Act 3: The Fate of the Empire, you and your heroes now seek assistance from the mountain kingdom of Lorenz, but King Leo proves troublesome indeed. He demands your heroes lead an expedition to the cultists’ hollow mountain. Unfortunately, his secret dreams and weaknesses threaten your mission, and your heroes must flee on Pegasus-back in an exciting aerial chase against winged nightmares.
Your heroes make their way to the imperial capital, but the court is in turmoil. You have the unique opportunity to shape the empire’s response to the crisis. Can you organize and unify the empire? Can even the massed forces of humankind stave off the looming disaster? Or is all the world fated to end up in the gullet of the monstrous Sleeper – Tsathoggua himself.
In the fourth and final Act of Big Sleep, Lullaby, Tsathoggua’s rampage continues unchecked. Your heroes must delve deep into the caverns whence the Great Old One emerged. Here, you encounter ancient subterranean civilizations and primordial beasts. As you make your way to the lightless realm of N’Kai, Tsathoggua’s origin, you find terror, abomination, and stygian vaults. But somewhere in this nightmare realm is the secret behind the Sleeper’s power. Only you and your heroes have the skills to obtain it, and the knowledge to use it. But Tsathoggua is also aware and alert – will you be ready for the final showdown with the titan itself and its army of slithering monsters?
