Coriolis: The Great Dark is a Free League TTRPG of middle eastern-flavored sci-fi, featuring intrepid explorers investigating mysterious alien relics in a space frontier known as the Lost Horizon. The game is a sequel to Coriolis: The Third Horizon, a sc-fi ‘tales of the Arabian knights’ TTRPG that I love.

The Fractured Library is a 124-page hardcover collection of five adventures for Coriolis: The Great Dark. These are dungeon crawl-style/exploration-focused adventure sites, designed to work as one-shots or incorporated into the Flowers of Algorab boxed set campaign. They include:

• The Fractured Library – the party escorts a mysterious cryo-pod to a secret research facility where a failed project has torn a hole in reality. Meanwhile, a bunch of zealots intend to take the cryo-pod to further their own ends. The adventure includes a new starship – the Kumaranti – with full deck plans and specs, which can be used by the PCs in other adventures, and new weapon types.
• The Octagon of Khouri – the party helps to find an estranged daughter in a jungle-filled crater which hides a devastating weapon of mass destruction.
• The Temple of Tomorrow – the party must climb to the top of an ancient alien pyramid while contending with cultists and spies. New weapon types are included.
• The Helesto Troika – the party is trapped with an art critic and mathematician inside an alien relic that forces them to relive a crucial moment of ancient alien history.
• The Singing Moon – the party must investigate a remote signal station on a small moon that mysteriously went silent.

As with all Free League books, the layout, art, maps, handouts and writing are top notch (although, as with many Free League books, each adventure is a little “over-written” with a fair bit of repetition of information that could have been cut back with tighter editing. This is an issue for most major publishers’ adventures, however). The Fractured Library is a good addition for any GMs running Coriolis: The Great Dark campaigns. If you don’t own that game, a little bit of work would make these adventures suitable for Mothership, Traveller or Stars Without Number. Following is a video preview.
