I rarely if ever get to see 17th-18th century fantasy, and I rarely get to see a serious longform fantasy epic, so I'm throwing my hat in the ring. The Concord Initiative follows an Italian/Spanish-style-Empire in decline, whose young and desperate king tasks his most loyal champion, Gasparro Cavallo, with an unenviable task: to lead a motley team of exceptional but villainous criminals in a state-sponsored bid to reassure the restless citizenry, inspire nationalistic energy, and solve the many crises of the Empire. Cavallo leads the growing Initiative against suicidal cults, antagonistic revolutionaries, and the many other insatiable powers that are salivating over the Empire's vulnerability.
As for recommendations, my most recent joy has been this delightfully eerie comic, done in the style of 12th century wood carvings depicting Christian-Pagan fusion cosmology and motifs. Fascinating and unsettling.
