A Poison Tree


A Poison Tree is an epic campaign for Trail of Cthulhu, a generational saga that spans the globe and 350 years of history.

The players take on different roles across five chapters and three interludes, beginning in rural Wales in the seventeenth century, passing through settings as diverse as revolutionary-era Massachusetts, South Africa in the 1890s, England at the start of World War I and Berkeley in the psychedelic throes of the 1960s. The campaign culminates in world-changing events in the present day, as the players correlate all of their findings, and decide on the destiny of humanity itself!

The varied time periods and the strange abilities of the Whettall family, whose tainted bloodline drives the story, have demanded some tailoring of the GUMSHOE mechanics. The campaign features new Professions and Abilities tailored to each setting, providing foundations for evocative and period-appropriate characters. Many investigators will be members of the Whettall bloodline, able to tap into strange abilities that are as much curses as boons. These abilities grow in strength and strangeness across generations, providing entertaining twists, even for experienced Trail of Cthulhu players.

A Poison Tree is written by Matthew Sanderson, Paul Fricker and Scott Dorward, who have been developing it for the last five years, and are now in the final stages of internal playtesting. While this isn’t the first campaign they have co-authored, it is the most ambitious in size, scope and structure.

    Hi, i was just wondering how this project is going. It has been a while since the last update :)

    • Cat Tobin says:

      Hey Dusan, thanks for the question! The writers are hoping to have the full game playtested by the end of this year. At that point, they can start writing up a full first draft of the text; we’re hoping to have that ready for external playtesting in April or May 2018. Our goal is still to release it in December 2018.

    Love the assumption of three-hour sessions, which is exactly what mine average to. Adulthood is the worst.

      Hi Ulf. We’re currently working on getting a playtest version ready, but we won’t be playtesting this until 2021. Thanks, Becky.
