Day one of Black Library’s 2016/17 12 Days of Christmas campaign brings us a free 40k micro-short story in the shape of Graeme Lyon’s The Librarian’s Acolyte. In the Ultramarines’ Librarium within the Fortress of Hera, Acolyte Loraeus is welcomed into the Librarius by Chief Librarian Tigurius himself. With his training due to start soon Loraeus is given a fairly straightforward first task, but events quickly spiral out of control and he’s forced to rely on his wits as well as his newfound power to deal with the escalating situation.
