Grimoire

No. It is a multi-author dark fiction and horror anthology, the first volume, curated under Lüthi's Sentinel Creatives. Contributors include C. L. Werner, Madison Kilian, Erica Schaef and H. P. Lovecraft, alongside Lüthi's own work.

A wide range, from medieval horror and Lovecraftian cosmic dread to monstrous Kaiju, accursed djinn and pestilential priests. The tones run from subtly unsettling to openly frightening.

Lovecraft's fiction is in the public domain, and the collection places his classic cosmic horror alongside new stories working in the same dark tradition.

Not directly. It is a standalone anthology rather than part of his Plagueborne or Pierre-and-Remi books, though it shares his taste for medieval and supernatural horror and draws on his Sentinel Creatives circle.

Yes. Grimoire was released in audiobook through Sentinel Creatives with a full cast of narrators.
