From publisher's webiste: Bon voyage! You are about to depart on ten journeys into the unknown, following the trail of Cthulhu to isolated Pacific islands, into the icy wastes of the Arctic, through jungles and war zones and even off the Earth itself. In the blank spaces of the map, dark deities flourish and evil festers… but the truth waits to be discovered, secret knowledge that man may not be meant to know but that Miskatonic University covets. Into that mystery your Investigators go, armed with gun and camera and notebook, risking their own survival to keep those blank spaces from swallowing up the world. Hurry on board — the gangplank is going up! The Mythos Expeditions are a collection of adventures for Trail of Cthulhu, designed to be run as a stand alone with new rules tailored for expeditions or as part of the Armitage Files campaign setting in the core rules. Take your Investigators on an expedition into the dense jungles of central Africa, trek through the arid wastes of the Gobi desert, and clamber through the lost cities of South America. Your travels will you take you through the skies and across the oceans, into the lava caves of New Zealand and the frozen peaks of Patagonia.
