Three 1920s scenarios for Call of Cthulhu. The first two, 'The Trail of Tsathogghua' and 'The Curse of Tsathogghua' are linked into a short campaign. The third, 'The Haunted House' is unconnected.
In 'The Trail of Tsathogghua', investigators join a scientific expedition to Greenland to examine a strange wall found protruding from a glacier.
'The Curse of Tsathogghua' sees investigators following a trail of clues in Canada which could lead them to the last survivors of a mythical race.
'The Haunted House' is a traditional ghost-busting scenario.
