Arc 19The Vengeance Expedition
William gathered the UNSC and Umbrella forces for an expedition against Yuri Marin, whose fleet and defenses they destroyed before invading Hozette-4d. The ground assault reached City Five, where William prepared to lead Nova, Keisha, John, and Carl toward Yuri’s palace.
- Ivan and Umbrella’s forces defeated Yuri’s attack near UV Ceti, then William ordered the fleets to capture the disabled ships and locate Yuri’s base.
- Tina’s team identified Hozette-4 as Yuri’s base, and William assembled the Vengeance Expedition while reorganizing the Astartes and requiring the UNSC to sign a Confidentiality Agreement.
- William departed for Hozette-4 with a thousand-ship fleet, while Halsey warned that Yuri might use captured Astartes to create clones, awaken psychic abilities, or develop a giant biological mecha.
- The Expeditionary Force emerged from Warp Space and destroyed Yuri’s fleet and orbital defenses, with William, Ivan, and the God Bodies helping seize control of the system.
- William’s forces landed near City Five, where Elizabeth Green’s alien swarm overran Yuri’s southeastern defenses and withdrew as Umbrella and UNSC troops began landing.
- The Astartes and other ground forces routed Yuri’s defenders, while William used gas to incapacitate mind-controlled civilians and Serena detected a vast underground complex beneath City Five.
- William equipped Nova with a custom Hostile Environment Suit and Keisha with ornate Power Armor, then ordered Serena to bombard remaining strongholds and sent Ivan and Athena to guard City Five.
- William, John, Carl, Nova, and Keisha flew toward City Five as Mylon’s troops held their position near Yuri’s palace under attack.
