And Warmaster Horus, being at the zenith of his power, is tormented by vague doubts: why the hell was his presence again required on the planet Davin, conquered sixty years ago! Betrayal...

On the fragile bridge between life and death, his decisive battle took place with the lying gods of Chaos. This was the day when Horus fell.
