About this episode
The episode explores the history and strategic significance of Betalis III in the Warhammer 40K universe, detailing its past and the events leading up to the Betalis III Campaign.
We start our dive into the Betalis Campaign with a look at the history and strategic significance of Betalis III, an icy mining world illuminated by a vast blue giant, detailing its origins as the doomed home of a young reptilian xenos species destroyed long ago by Irillyth and Craftworld Mymeara, the planet’s later rediscovery by the Imperium during the Omniel Crusade, and its harsh colonisation under exploitative debt-labour conditions. We recount the discovery of an ancient Aeldari craft entombed in the ice, the subsequent Ordo Xenos lockdown, and the world’s transformation into a major industrial resource hub whose population remains bound by hereditary servitude. We then shift to the events leading up to the 894.M41 Betalis III Campaign—known to the Eldar as the Battle of the Dawning Twilight—where multiple Aeldari factions converge on the system and the Imperium responds by mobilising Cadian and Elysian regiments, Titans of Legio Gryphonicus, and eventually the astartes of the Space Wolves Patreon Merchandise Quartermaster Listen Ad-Free SHOW IMAGES The Doom of Mymeara The Betalis System Aeldari…
