Garro: Oath of Moment (Audio Drama)

Garro: Oath of Moment is the second audio drama for the Horus Heresy Series that was not originally released as part of an anthology or other release. Garro: Oath of Moment was released in both compact disc and MP3 formats and was written by James Swallow and performed by Toby Longworth. It was later re-released in an enhanced audio edition in 2015, but can still be bought as a stand-alone audio drama. This story, and all other Garro audio drams and short stories were later published in printed form in the Garro main series anthology novel.

He soon finds himself back amongst the stars and on the fields of battle, thrust into a warzone where the Ultramarines are purported to be battling a greenskin invasion. Once again Garro must fight for survival, but now he also fights to achieve a higher purpose...
