Chapter Master - Blood Angels: Dante - Dante, the commander (Chapter Master) of the Blood Angels, is considered to be the oldest living Chapter Master within the Adeptus Astartes at over 1,300 standard years old. He is believed to be the oldest living Loyalist Space Marine with the exception of those Space Marines sustained by the cybernetic technology of Dreadnoughts, the use of temporal stasis or other technological means of extending human life. Lord Commander Dante's exact age is unknown and he is suspected by some members of his Chapter to be even older than his 13 centuries.Kadeus - Kadeus was a former Chapter Master of the Blood Angels. He took part in the catastrophic Space Hulk cleansing operation in 996.M40 that came to be known as the Secoris Tragedy. Kadeus, alongside Captain Dante, were one of only fifty surviving battle-brothers able to fight their way off the Genestealer-invested hulk. He was later chosen as Sangallo's successor as Chapter Master and lead his Chapter from the brink of extinction. During his time as Chapter Master, Sangallo wielded the relic blade Challenger, and famously battled the Tzeentch Daemon Prince Sethselameth after it emerged on the Battle Barge Bloodcaller. In the subsequent battle, Kadeus managed to banish the Daemon back to the Warp but was mortally wounded in the process. A beautifully painted mural was later created on the vessel to commemorate this famous battle. Kadeus would die of his wounds in the great audience chamber (the Grand Annex) of the Blood Angels' fortress-monastery on Baal. Before his death, Kadeus named Dante as his successor and gave him the Axe Mortalis.Sangallo - Sangallo was a former Chapter Master of the Blood Angels. He led a large force of the Chapter to battle in the Secoris Tragedy, a catastrophic Space Hulk cleansing operation undertaken by the Blood Angels Chapter in 996.M40. The entire Chapter deployed when a Space Hulk appeared in the Secoris System near Baal. However, the Blood Angels discovered tens of thousands of Genestealers in hibernation. The resistance the Sons of Baal encountered was fierce, and Sangallo was tragically killed. Among the fifty battle-brothers who managed to escape the battle were Captains Dante and Kadeus. Kadeus would go on to take Sangallo's place as Chapter Master and lead his Chapter from the brink of extinction.Castivarus - Successor of the short-lived Chapter Master Kalael, Commander Castivarus is most remembered for leading the so-called Shield of Sanguinius (a combined force comprised of the Blood Angels, Astra Militarum and Knights of House Griffith) against a massive Ork WAAAGH! in the Redhaven System. Perceived and masterfully coordinated by the Chapter Master, the Imperial defence successfully halted the WAAAGH! and was utterly destroyed.Kalael - Kalael was the short-lived commander of the Blood Angels in the 35th Millennium. Per Chapter tradition, following the death of his predecessor, the Captain of the 1st Company was elevated to the position of Lord Commander. When Captain Kalael rose to the rank of Chapter Master he succumbed almost immediately to the Black Rage, throwing the Blood Angels into a spiritual and organisational crisis. This led to the restructuring of the Chapter Command, which incorporated the Sanguinary Priesthood and Reclusiam as a part of the Blood Angels' higher echelon. This structure means that the Sanguinary High Priest and High Chaplain take joint temporary rule in the event of the Chapter Master's death. By holding temporary command, the High Chaplain and Sanguinary High Priest can test the will and worthiness of the new candidate to ensure that such a rash and unfortunate appointment does not occur again.Belarius - In some contradictory legends of the Chapter, Belarius was the first Chapter Master of the Blood Angels after the death of their primarch at the hands of Horus during the Siege of Terra. A revered Chapter hero during the Great Crusade and Horus Heresy eras, he was given the legendary weapon known as the Blade Encarmine by Sanguinius and was unanimously hailed by his battle-brothers as the Angel's successor in guiding the Chapter into an uncertain future following the end of the Heresy. This name may be an alternate or legendary name for Raldoron, who was the true first Chapter Master of the Blood Angels following the end of the Heresy and the death of Sanguinius.Raldoron - Raldoron, known as the Blooded, was the legendary First Captain of the Veteran 1st Company of the IX Legion during the Great Crusade and Horus Heresy eras. He was one of the primarch's most trusted men and carried many honours alongside his stewardship of the elite 1st Company, the Protectors, a responsibility hard-won through decades of war in the Emperor's name. Raldoron was Equerry to his Legion's primarch and held the then-new honourific "Chapter Master", serving in an advisory role to Sanguinius. In some contradictory legends, it was Raldoron who was elected the first Chapter Master of the Blood Angels following Sanguinius' death at the hands of Horus. Other legends state it was Belarius. These two individuals might be one and the same, but Imperial records from this time are fragmentary and unreliable at best.
