Sean and Chris were born on the world of New-Gen, the twin sons of Gabriel, leading scientist in the field of nanotechnology, and his wife Thea.

They were mere infants when Gabriel's apprentice, Sylvester Deadalus, betrayed his mentor and released an enormous swarm of nanobots onto the populace.

[2] As they got older, Sean began having nightmares about a man they didn't recognize, which Chris dismisses as merely bad dreams.

[4] The twins, having been infants on New-Gen when Deadalus' swarm infected the population, have latent, dormant powers, the full extent of which has not yet been revealed.
