Phall System

The Phall System is the location of the Battle of Phall, a void engagement of 007.M31 between Imperial Fists and Iron Warriors forces. It is classified under the Ultima parent. Phall I and Phall II are lightly populated rocks, and the conflict was decided between fleets rather than on the surface.

In 007.M31 a third of the Imperial Fists, commanded by Alexis Polux, fought Perturabo’s Iron Warriors at Phall until Dorn recalled them to Terra. The system later hosted the Last Wall protocol, which summoned Imperial Fists successors during the War of the Beast. No hive settlement or ground massacre comparable to that at Isstvan is recorded there.

The Phall System remains notable as the void battle between the Imperial Fists and the Iron Warriors that Dorn could not afford to bring to a conclusion. Unofficial fan summaries retain the Ultima parent and do not relocate the entry to Inwit.
