Solar War: Fall of Luna
Place: Luna · Segmentum Solar
Traitor victory Abaddon rams the lunar defence ring with the “War Oath”; Battlefleet Solar is scattered.
The Thousand Sons and Word Bearers seized the Comet between Venus and Terra for a great sacrificial rite devised by Lorgar for an unprecedented conjunction of the luminaries. Abaddon’s Sons of Horus appeared above Luna and rammed its defensive ring with the flagship “War Oath”, punching a 20-kilometre breach. At the height of the rite reality split open, disgorging tens of thousands of traitor ships, which destroyed and scattered Battlefleet Solar; on the surface Justaerin with the Word Bearers seized the Selenar gene-seed technologies.
