The Aeldari Craftworlds are the last great vessels of a doomed civilisation, continent-sized ships that carried the more temperate of the ancient Aeldari away from their empire before it collapsed into ruin. Each is a world entire, its towering domes sheltering forests, cities, and shrines, its hull threaded with the webway and crowned by an infinity circuit in which the souls of the dead are preserved against a predatory afterlife. To walk a craftworld is to walk among a nation that refuses to die.
Though scattered across the void, the craftworlds form a loose civilisation bound by shared dread and shared blood. There is no central throne; each is a sovereign society governed by its own councils of seers and autarchs, and each has developed a distinct character shaped by how narrowly it escaped destruction. Some are grim and fatalistic, others militant and proud, others still cling to gentler traditions, but all order their lives around the disciplined Paths that keep the Aeldari from the emotional excess that once damned their kind.
The craftworlds cooperate rarely and reluctantly, for their seers guard visions they will not share and their peoples nurse ancient grudges. Yet in moments of true peril they can act as one, their farseers weaving a common thread of destiny across light-years. This fragile unity has grown more vital since the tearing of the Great Rift, which severed webway routes and left craftworlds isolated amid rising darkness.
Every craftworld is engaged in the same desperate calculus, spending the lives of a dwindling people with miserly precision to steer the galaxy away from catastrophes only they foresee. Theirs is not an empire seeking to grow but a civilisation seeking to endure, and their long war is fought less for victory than for the simple, bitter privilege of surviving one more age.
