Changes

*In the novel [[Fear to Tread (Novel)|Fear to Tread]], [[Horus]] witnessed [[Sanguinius]] struggling then killing one of his Blood Angel legionnary, [[Alotros]]. When Horus asked Sanguinius the reason he murdered one of his sons, The Angel first refused to answer his brother. Insisting, Horus finally had his answer from his brother: Sanguinius transmitted a genetic flaw to his Blood Angels, known as the [[Red Thirst]], which turns a legionnary into a mindless killer, leaving him no other choice than killing Alotros. When Horus asked Sanguinius why he never talked about that with his Primarch brothers and, above all, why he never asked for help from their creator, the [[Emperor]], Sanguinius replied he feared the most radical solution his father could propose: "You know the reason! [...] I will not be responsible for the erasure of the Blood Angels from Imperial history. I will not have a third empty plinth beneath the roof of the Hegemon as my Legion’s only memorial!’{{C|28}}
