Diolus Akrodius

Diolus Remulak Akrodius was a Custodian of the ancient Legio Custodes during the Great Crusade and Horus Heresy eras. Akrodius was a Custodian-Guardian of the Vanek-Aeterna Sodality and a member of the chamber of the Dankanatoi.

History
Akrodius began his life as a member of the Legio Custodes chamber known as the Ephoroi. Akrodius was part of a sodality which was sundered during the Signus Campaign of the Horus Heresy, his brothers-in-arms meeting their deaths at the hands of the vilest daemons of the Warp during the heroic defence of the Red Tear.

After the fateful events that took place at Signus Prime, the wounded Custodian was kept ignorant of the existence of the Imperium Secundus, remaining aboard the Red Tear with the other wounded among his kin while the Blood Angels Legion lingered in the Realm of Ultramar.

When their force would eventually return to Terra, the recovered Akrodius would learn of the depth of disloyalty involved in the Horus Heresy and vow, alongside many of his peers, not to rest until every last hint of treachery was expunged from the Imperium.

Akrodius would go on to become one of the first representatives of a newly founded chamber of the Legio Custodes, active during the final years of the Horus Heresy, that of the Dankanatoi.

Unleashed upon the last dregs of Horus' failed rebellion as they fled Terra, these warriors proved a potent weapon for the battered Loyalist host. Indeed, even in the long years of strife that followed the dark age of the Horus Heresy they remained active, hunting Traitors and xenos invaders alike long after the official end of the Great Scouring.
