One of the new breed of "tweak" superbabies, Marcus Alfonse Lee fulfilled the hopes and dreams of his successful software engineer single mother Victoria, and more. Chairman of the board at 12, he was quick to see the potential for venture capitalism in the buckyboard-driven space rush of the late 21st century c.e. (early 2nd century AT).
By 2130 (160 AT)the family business, Lee Interorbital had a fleet of LEO shuttles. By 2150 (180 AT)they had established their own orbital habitat, - a combination of theme park, business hotel, and tax and data haven, officially called Elysium but more affectionately (and sometimes not so affectionately) known as Marcus World. This was to be the first of a number of "company biospheres" that were later to dot the asteroid belt and the surface of the half-terraformed Mars.
Even after four successful rejuvenation treatments, Lee ruled the corporation with an iron hand, investing heavily in cutting edge biotech, asteroid mining, and even the new interstellar colonization program, a stormy sea that had already sunk many lesser investors. By the start of the 24th century c.e. (early 5th AT) he seemed to be becoming increasingly rigid and inflexible in his decisions, a common problem among many of the early over-rejuved tweaks.
A series of catastrophic business decisions saw stock plummeting and the company brought to its knees. A corporate takeover by the aggressive AI in charge of Hyperion Interplanetary saved the company but ousted Lee. Bitter and disillusioned, he defected to the Gengineer Republic, and his final fate has never been determined (most of the Genetekker records were lost in the wake of the nanoswarms).
