Chapter of the Avenging Sun is a part of The Bright Custodians and both are parts of Caorran.
Generally just called a Custodian, these are the rank-and-file members of the Order who have survived the joining trials and tests.
Custodian Commander of the Chapter of the Avenging Sun
“To bear the Sun upon your back is to cast a shadow vast enough to drown empires.” — Sidereus Nuncius, Custodian Commander of the Avenging Sun
The Custodian Commander of the Chapter of the Avenging Sun is the supreme commander and spiritual war-leader of the Lowlands Chapter of the Bright Custodians. This mantle is borne by the most devout and battle-hardened among the Custodians, a paragon of martial might and theological conviction. The Custodian Commander does not merely lead the Chapter in war — they embody its purpose: the relentless extermination of the Imperium’s enemies in the name of Aeternum Solis.
The responsibilities of the Custodian Commander extend beyond battlefield command:
"What does it mean to bear the mantle of a Custodian?
What is the essence of death?
What purpose does ending life serve?
For what cause do we wage war?
What defines the barbarian?
And the daemon?
What of the heretic?
Who is the Apotheon?
And the Solar Ecclesiarch?
What binds us?
What vows did we swear?
What awaits our foes?
Who shall triumph over darkness?
Who wields the blades of divine justice?
Who are the Scions of Sol?
Catechism of the Avenging Sun
The Chapter of the Avenging Sun is an Asrian Chapter of the Bright Custodians, situated in the Lowlands region. Renowned for their fervent dedication and zealous ethos surpassing even their peers among the Custodian Chapters, they have garnered a reputation for zealous devotion. Established by Ayma Argovius during the Battle of Naxos, she led the vanguard, personally spearheading the charge.
Their operational center resides within the venerable bastion of Baile Helibore. From this stronghold, their vigilant patrols set forth, standing watch along the routes traversed by pilgrims en route from the Imperium Asraniae. Their mission remains unwavering – to shield these seekers of sacred destinations from any potential threats.
Following Ayma Argovius's passing, leadership of the Lowlands Chapter transferred to Sidereus Nuncius, coinciding with a shift towards isolationism, partly due to their geographical remoteness from Sunspire.
