Neben dir genannten Läuterer fällt mir zusätzlich nur dies ein, Cthulhu Apocalypse: The Dead White World.
Eher eine Kampange/Setting mit der Pflanzenprämisse.
The first part of the highly anticipated Cthulhu Apocalypse campaign.
The Investigators are rendered unconscious by a train crash. When they wake they discover the world has died. White flowers cover the ground and they see, beneath the delicate petals, the faces of the dead. No other human is in sight, everyone is gone.
The struggle to survive the apocalypse takes the Investigators through Britain, across the sea to America and beyond the veils of reality.
The Dead White World contains the first three scenarios for Cthulhu Apocalypse by Graham Walmsley, author of The Purist Adventures.
