But he will not find it unguarded - the Ardent Reef, an encircling ring of gun bastions and asteroid bases, is but one amongst many such lines of defence. Captain Arcadese of the Ultramarines finds himself in command of a host of his battle-brothers, as the renegade Warmaster's fleet launches its final assault on the Throneworld. Will he hold the line even in the face of almost certain death, or will his own loyalty waver in those final moments?ABOUT THE BOOKPublished for the first time in English, this Horus Heresy short story has previously appeared in the French Games Day Chapbook 2012.
