Lair of the Zo’hamir

Lair of the Zo’Hamir is an OSR adventure designed to immerse your party in 3–4 thrilling sessions of danger, horror, and survival. This module introduces the titular Zo’Hamir for the first time: a tribe of entropic lizardfolk obsessed with the triumph of the strongest and the unstoppable force of evolution.

Explore the harsh desert, following the bloodied trails left by those responsible for brutal massacres of humans and animals alike. Descend into the hidden Domain of the Zo’Hamir to uncover the terrifying reasons behind their bloodlust—only to find yourself trembling when the truth is revealed. A world-shattering cataclysm looms on the horizon, and only you—mere adventurers—stand in its way. Whether you succeed or warn those with greater power is up to you.

A Gritty, Unforgiving Adventure

Lair of the Zo’Hamir embraces the post-TSR OSR style where discretion is the better part of valor, and the only good fight is the one fought dirty. Expect to face unique monsters, outwit traps set by instinctual hunters, and get your hands filthy as you delve into a dungeon where every room could be your last.

Encounter the utterly alien mindset of the Zo’Hamir and witness horrors that will make your teeth chatter—assuming you still have teeth when it’s all over.

Should you survive the Lair, your choices will shape the future. Will you be hailed as the saviors of the village? Or will you herald a cataclysm that could wipe humanity from these lands?
