40k Space Marine Legions List compiles core lore and reference-style notes on the Emperor’s creation of the Legiones Astartes during the Great Crusade. It explains how the Astartes were shaped from gene seeds tied to individual Primarchs, refined and mass-produced by gene cults, and formed the spear tip across the galaxy. It also summarizes key historical turning points, including the Horus Heresy alignments, the flight into the Eye of Terror, and later fragmentation into forces.
