"Heresy grows from idleness."
Former bureaucrat of Wookieepedia. Currently furiously reading through the Horus Heresy series.
Horus Rising, written by Dan Abnett and published in April 2006, is the first work in the Horus Heresy series. The novel focuses on the Space Marines in Warmaster Horus's inner circle prior to his betrayal. The plot of Horus Rising is directly continued in the later novels False Gods and Galaxy in Flames—together, these works form a narrative trilogy that serves as an introduction to the characters and setting of the series.
