Arc 18The Rust Plague and Warp Gate
Atia’s Thousand Sons and Phelps’s Death Guard attacked Brevis, while Dominic’s forces fought to contain the Warp domain and the Rust Plague. Lynn purged the Gemstone’s Machine Spirit of corruption, but the Thousand Sons’ assault on Midtown and a Chaos Undivided blockade at Saint Garus Castle left the conflict unresolved.
- Bishop Jensen and Colonel William prepared Midtown’s defenders as Rena mobilized the undercity forces, and Atia arrived through Warp rifts with his Thousand Sons warband.
- Phelps’s hidden plague invasion slaughtered Keller’s squad and spread through the Gemstone’s lower decks, overwhelming successive Imperial defenses.
- Dominic led the defense of the machine temple, where Sisters of Silence weakened Phelps’s Death Guard and Dominic beheaded Phelps.
- Barlow and Coren revealed Phelps’s plan to corrupt the St. Garus Knight House and search for a Great Conspirator spell fragment, then killed themselves rather than remain corrupted.
- A surviving plague seed infected the Gemstone’s Machine Spirit, and Dominic entered its consciousness while Lynn used Sorine as an intermediary to confront Phelps.
- Lynn and the Machine Spirit destroyed Phelps and the Rust Plague, after which Lynn subdued the Machine Spirit and Dominic ordered the lower decks searched.
- Dominic offered orbital support against Atia’s attack on Midtown as Rena reported that the Warp gate would soon close and Chaos Undivided cultists had blockaded Saint Garus Castle.
