Phall I

Phall I is a lightly peopled agri-world and the namesake pin for the Battle of Phall. A third of the Imperial Fists under Alexis Polux fought Perturabo's Iron Warriors in the void here in 007.M31 until Dorn called them home to Terra. The system later hosted the Last Wall protocol that summoned Imperial Fists successors in the War of the Beast.
