Cobden-Bright
Cobden-Bright were quantum entangled agents of the Great Houses, technically one person with cells perfectly mirrored in two separate bodies. Cousin Isabella stated they were "two brains but one mind." The one mind was able to control both bodies independently with bronze "barbed wire" circlets.(PROSE: Spinning Jenny)
The conjoined pair were sent to Strines in 1854 to destroy the time bubble formed by the conflict between Spinning Jenny and Baron Samedi. Isabella managed to kill the Bright half with her shadow weapon, throwing Cobden's body into agonizing disarray, incapable of regeneration. Traveling to before the time bubble's formation, Isabella used Cobden's biodata as bait to draw Spinning Jenny and Baron Samedi to Strines in the first place. (PROSE: Spinning Jenny)
