===Signus Prime and Ka'Bandha===

At one point during the Great Crusade, Sanguinius and the Blood Angels were tasked by Warmaster Horus with reclaiming the Signus Cluster from a supposed [[xenos]] infestation and liberating the humans there from their oppressors. However, when they arrived, they found that the entire system had been consumed by the evil influence of the [[Chaos Gods]], and specifically a [[Keeper of Secrets]] calling itself Kyriss [[/d/|the Perverse]]. This was actually a trap set by Horus in an attempt to eliminate Sanguinius early on, because he feared him more than any of his other fellow Primarchs as he was nearly his equal in both combat and commanding. In fact, at one point right before his fall to Chaos, Horus actually admitted to a Remembrancer that he thought that Sanguinius should have been named Warmaster instead of him. Also this was after Horus's corruption and Sanguinius was not aware of the Isstvan conflicts at the time. Long story short, the Blood Angels were stranded in-system, caught off guard, and lost a lot of Marines, ships, and crew, but eventually regrouped and conquered the armies of cultists and Chaos [[daemons]] in the Signus system. Kyriss even manifested on the bridge of the Red Tear, the Blood Angels flagship, from the frames of [[Khorne|eight]] servitors, to taunt Sanguinius. This was also Horus's first true defeat, as there was no benefit gained from the campaign.

But a greater threat soon emerged: [[Ka'bandha]], a powerful [[Bloodthirster]] and one of [[Khorne]]'s greatest servants. He attacked the Blood Angels while taunting Sanguinius in the middle of the battle and claimed that Horus had betrayed him. Refusing to believe this, Sanguinius attacked in [[rage]], and managed to stab his sword right into the daemon's chest and wound him severely. Ka'bandha, almost beaten, distracted the primarch with the truth of horus’s betrayal. Ka'bandha then lashed out with his whip, ensnaring Sanguinius' legs and crushing them. Then, leaving Sanguinius alive for [[Plot armor|some]] [[rage|reason]] (perhaps fearful Sanguinius really would become an angel if he died), then charged off to slay a few hundred Blood Angels. The Red Thirst, already a problem for the Blood Angels, was exacerbated by the psychic shockwaves of each of his sons dying, and Sanguinius vowed that he would take vengeance on Ka'bandha for this atrocity. In the Chaos temple at the centre of the battle, Sanguinius duelled Ka'Bandha again, ripping off a wing and then throwing him off a platform and back through a portal into the realm of Chaos. To top it off, Sanguinius then faced Kyriss and beheaded that sick fuck, promptly ending his rule and Chaos' hold on the system.

In a moment of hesitation, Sanguinius was tempted by the offer of becoming a Chaos Champion in exchange for curing the Red Thirst and Black Rage. Seeing this, Meros jumped straight into the portal, telling his Primarch not to give up hope, turning into the Daemon known as the Red Angel (Meros' geneseed would later be transplanted onto Rafen)

Inspired by his sacrifice Sanguinius was able to say no to the Daemons. This gave him the courage to resist the temptation of Chaos later on when Madai offered the same deal
