Chaosium has released The Sutra of Pale Leaves: Twin Suns Rising. This supplement is set in Japan of the 1980s, an all-new setting for the Call of Cthulhu roleplaying game.

The book contains three all-new scenarios that are suited to stand-alone play, or strung together as part of a larger campaign set in 1980s Japan.

The Sutra of Pale Leaves was written and produced by The Sons of Singularity in collaboration with Chaosium. Under license from Chaosium, The Sons of Singularity have produced Call of Cthulhu releases that have achieved critical and popular acclaim. These include The Sassoon Files, Journal d’Inochine, and The Blessed and the Blasphemous.

A second volume for this setting, The Sutra of Pale Leaves: Carcosa Manifest, will be released later in 2025.
