In 998.M41, doom came to Eireius when a tendril of Hive Fleet Leviathan fell upon it, and Tyranids were soon rampaging across its floating jungles and vapour islands. A detachment of Imperial Knights from House Raven were the first Imperial reinforcements to reach the Agri World, and they rallied its beleaguered defenders as they battled the Tyranids. However, not even the might of House Ravens' Knights could save the world from the ravages of Hive Fleet Leviathan, and Eireius soon fell, though the Knights' bravery bought time for its surviving population to escape into the void.
- Eirebian — floating city. Knight Lornarus defended it for ten days during the Tyranid attack, enabling population of city to escape.
