Few progression fantasies have travelled as far from their humble beginnings as Mark of the Fool. Its author, J.M. Clarke, began posting the story chapter by chapter on the serial fiction platform Royal Road during the pandemic, where it drew a devoted following and millions of reads long before it ever reached print.
Clarke writes in the weak-to-strong tradition that defines progression fantasy, a subgenre built on visible, incremental growth in power and mastery. His hallmark is a carefully engineered magic system paired with warm, character-driven storytelling and a streak of dry humour. The world owes a clear debt to tabletop role-playing games, with its academies, spellcraft and questing parties, yet the emotional core stays firmly with its young protagonist and the makeshift family he gathers around him.
The result has crossed comfortably from web serial to a completed ten-book saga, winning readers among fans of magic-school adventures and LitRPG alike, and standing as one of the more striking self-publishing success stories of recent years.
