Slaves to Darkness

The Dark Gods do not need daemons to conquer a realm: they need believers, and mortals have always volunteered. The Slaves to Darkness are Chaos as most of the Mortal Realms actually meet it: not horrors from beyond the veil but human tribes from the frozen hinterlands, oath-broken soldiers, exiled kings, and knights in black baroque plate who looked at the powers ruling existence and decided the strongest were the only ones worth kneeling to. Most swear themselves to no single god but to Chaos Undivided, the pantheon entire, courting Khorne's rage in one battle and Tzeentch's cunning in the next, bowing to each exactly as long as ambition requires.

Their whole civilization is a ladder, and the ladder is called the Path to Glory. A tribesman who kills well enough may be granted plate that never rusts; a warrior who kills better may feel the gods' gifts crawl beneath his skin as new muscle, scale, or fire. Champions rise, gather warbands, and gamble everything on the pantheon's attention, because at the ladder's top waits apotheosis, an eternity as a daemon prince, and beneath every rung waits the other outcome: the mindless, thrashing ruin of a Chaos Spawn. The gods find both results equally entertaining. The climbers know it, and climb anyway.

Over every one of those ambitions falls the same long shadow. Archaon the Everchosen, the Three-Eyed King who ended the world before this one, rules from the Varanspire at the heart of the Eightpoints, the dread crossroads whose arcways open onto every Mortal Realm. Every damned legion marches, knowingly or not, in patterns he has woven; every warlord's conquest feeds a war that belongs to him; and the greatest champions the Path produces are harvested into his Varanguard, to ride ever after for his glory instead of their own. To walk the Path to Glory is, sooner or later, to discover that all of its roads run through Archaon.

The free peoples spit the word 'slaves' as a curse, and the hordes wear it as a trophy of irony, because they believe the enslavement runs the other way. To them the cities of Order are the true chains (walls, laws, tithes, and distant gods who demand faith and answer with silence), while the Dark Gods answer loudly, in gifts you can hold and wounds you can deal. It is the great recruiting lie of the Age of Sigmar, and it works: every city the hordes burn leaves survivors, and survivors remember which gods showed up. Among the Slaves to Darkness, damnation is not a punishment. It is a promotion.
