The Order of Merlin steps outside the academic setting of most Hundred Halls stories and into the enforcement side of the magical world. The three-book series follows agents who handle the cases that are too dangerous or politically sensitive for normal channels — magical crimes, rogue practitioners, and threats that could destabilize the entire hall system.
Published across 2023, the trilogy moves quickly from The Order of Merlin through Infernal Alliances to Tower of Horn and Blood. It gives readers a different perspective on the Hundred Halls universe, showing what happens when the rules get broken and someone has to clean up the mess.
