Victor Steinberg

Once celebrated across the Expander engineering world as a rare genius, Victor Steinberg was the beloved older brother of Mary—until the Great War shattered everything. He vanished without a trace in the aftermath, only to resurface as the feared fugitive known as 'The Dismantler,' a phantom capable of disassembling Expander units with terrifying speed and precision. Now embedded within the clandestine anti-Expander organization Spitsbergen, Victor is increasingly governed by a fractured 'Shadow' persona born from deep wartime trauma, fueling his singular obsession: the total annihilation of all Expander technology. His arc forms the beating heart of the second story arc, making him one of the most pivotal and complex figures in the series.
