The Complete Yig Snake Granddaddy (Acts 1-4), four-volume hardback campaign for D&D 5th edition
“In Yig Snake Granddaddy, the new Cthulhu Mythos for 5e campaign, evil serpent folk seek to bring back prehistoric times, complete with pterodactyls, dinosaurs, and other monstrous beings.
Act 1: Land Out Of Time
Yig Snake Granddaddy is an amazing campaign in which evil serpent folk seek to bring back prehistoric times, complete with pterodactyls, dinosaurs, and other monstrous beings.
In Land Out of Time, the first act of four, your player characters adventure into the wilds of Yilan, a primeval wilderness infested with carnivorous slime molds, gigantic crocodiles, and other lost horrors. There they encounter an evil serpent wizard, who prepares for an evil ritual beyond belief.
Betrayed, marooned, and hunted by super-intelligent enemies, can the heroes even survive, yet alone prevail?
Act 2: Against The Serpentfolk
Captured by the serpent folk, the heroes find an unlikely ally – a mummified-yet-living being from the distant past. Cut off from the outside world, and stranded in the wilderness of Yilan, the heroes must rely on wit & grit to survive, building themselves a stable base out here in nowhere.
But they must also bring the fight to the serpent folk, who relentlessly seek to destroy them, raiding with dinosaurs and worse.
In addition to raiding the heroes and their friends, the serpent men are not idle – they now begin to awaken other terrifying civilizations from the distant past, forging an alliance that may turn time itself topsy-turvy.
Act 3: The Prehistory War
The heroes are on the offensive, trying to undermine the ancients’ plans, but they can’t do it here – they must travel to the dreamlands to find new allies. But this is not all. Their ally, the mummified cat Dandelion, brings them into contact with a Yithian who opposes some members of his own race. Seeking to sabotage the Yithians, the heroes must mindswap themselves into molluscoid Yithian bodies. Can they trust their Yithian ally? No Yithian can be a true friend – he follows his own goals exclusively with obsessive skill.
Finally they must hunt and capture alive a legendary super-snake which their enemies seek to summon Yig himself! Can they beat the serpent folk at their own game?
Act 4: The Ancient Ages Again
With their enemies on the defensive, the heroes must try to knock both the Yithians and the Elder Things out of the war. But can they successfully campaign against entities who are wiser and more intelligent than even the smartest human?
Even if they succeed, it is to discover that nothing is more dangerous than a cornered snake. The serpent wizard plots to sacrifice an entire city to Yig and summon the Great Old One himself in an apocalyptic rain of deadliest venom. Can the heroes defeat Yig in person?”
