Phall I

Phall I is a lightly populated agri-world and the namesake of the Battle of Phall, fought between Imperial Fists and Iron Warriors in 007.M31. Its historical importance derives from events in the surrounding system rather than from its own population or economy.

In the engagement that bears its name, a third of the Imperial Fists, under Alexis Polux, fought the Iron Warriors of Perturabo in the void at Phall. The action ended when Rogal Dorn recalled the Imperial Fists to Terra.

The system later hosted the Last Wall protocol, which summoned successors of the Imperial Fists during the War of the Beast. Phall is therefore associated with two separate episodes in Imperial Fists history, although the world itself remains lightly populated.
