U.C Joint Military soldiers fighting Blackwatch soldiers on the streets of Seattle
The War for Seattle, also known as the Seattle Conflict and the Seattle Outbreak, was a conflict that occurred on Dei'ijikki Earth in the City of Seattle from August 15th, 3191 to November 15th, 3192 N.E (3744 to 3745 Dei'ijikii) that was fought between the United Civilizations, Blackwatch and William Jäger's Blacklight Army, with the UC claiming victory in the end, however it was a pyrrhic one as much of Dei'ijikki Seattle and the rest of Puget Sound reduced to ruins, with Seattle itself especially devastated to the point that the majority of it, some 78% of the city, was rendered uninhabitable due to the actions of both Blackwatch (which were wiped out in the process of the conflict) and Jäger actions.
Many later historians would point to the War for Seattle as a forewarning of the Infection War, starting a month and a week after the War for Seattle on December 25th, 3192 NE, not only due to the nature of the "conflict", that seversal outbreaks began in small parts of the Multiverse and spread out rapidly to become a string of multiverse-wide pandemics but also one of the key individuals that were directly the cause of the conflict, William Jäger.
