Folks who came along to The Horus Heresy Weekender event last week were treated to some advance releases from Black Library, one of which was Knight Errant, a collected box set edition of all the Horus Heresy Nathaniel Garro audio dramas released to date, along Ashes of Fealty, a brand-new original Garro story that ties into events from the end of my novel The Flight of the Eisenstein.
