Mad Cave Studios is proud to announce Our Soot Stained Heart, an atmospheric new series from debut writer Joni Hägg, co-written and illustrated by Stipan Morian.

This original fantasy series, brought to life with colorist Ropemann and Eisner-winning letterer Hassan Otsmane-Elhaou, fuses steampunk, frostpunk, and mythic folklore into a singular vision of fire, rebellion, and resilience. The result: the most thrilling adventure of the winter.

The Coalition is a city of wonder in the deep north, but it is ruled by the cruel Governor Glass and his factory lords. Coal is the lifeline of the city, and for honest workers like young Peggy Stones, life can be hard because of the nefarious quota. To get extra coal at the end of the year, you must be bad, every day! Peggy’s life is thrown into chaos when she is imprisoned and sent into exile, which begins a harrowing journey to the ends of the world to find answers that could change the world!

Our Soot Stained Heart delivers both the spectacle of an epic winter’s rebellion and the intimacy of a tale about empathy, community, and hope. 

Our Soot Stained Heart #1 drops December 10, 2025. Preorder it from your local comic shop starting September 19th!.
