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 are the first Imperial reinforcements to reach the Agri World and they rally its beleaguered defenders, as they battle the Tyranids. However, not even the might of House Ravens' Knights, can save the world from the ravages of Hive Fleet Leviathan and Eireius soon falls; though the Knights' bravery buys 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.
