The House of the Seven Gables was the result of Cousin Gable's experiments with the Army of One concept, through which he diffracted his timeline at five-year intervals to edit himself into six elder brothers aged such that when he was 41, his "siblings" were ages 46, 51, 56, 61, 66, and 71.
The six iterations, disguised by their variety of ages and weights, worked at Brookhaven's Hawthorne estate in a variety of jobs: the oldest, Rhett, was the butler; another was a gardener; the others worked as two odd-job men, a chef, and a valet. Brookhaven believed that, as his future selves, they would faithfully protect him to ensure their own existence.
When the House Military sent Chris Cwej to take dismantle Brookhaven's operations, he used his experience with the Cwejen to turn the seven Gables against their progenitor, promising them lives of their own. However, after the Hollywood Bowl shooting, official House Military instructions were that they should be killed on sight. (PROSE: The Book of the War)
