Seattle was a major city in the state of Washington, which is now part of the California Commonwealth.
History[]
Pre-Blackout[]
Maggie Foster was on a business trip in Seattle, Skyping with her two sons, Elliot Foster and Callum Foster, when the power went out.
Post-Blackout[]
At some point, Maggie left Seattle and walked all the way to the eastern seaboard in search of a ship to get back to England.
Eventually, Seattle became part of the California Commonwealth. The status of the city is unknown, however.
