Getting a Spartan into Dead or Alive 4
Nicole was born in the year 2531 in the city of New Legaspi on Mars. At six years of age she was abducted by agents of the Office of Naval Intelligence and conscripted into the Spartan II program. The Spartan II program was the UNSC's highly successful military project to augment and hone perfect soldiers.
SPARTAN-458's unit was preparing for a classified mission on Nassau Station when the ONI stealth ship Apocalypso tumbled into real-space – being carried along in the wake of a freak slipspace anomaly. The anomaly intersected Nassau Station; creating a semi-stable "bubble" in the space/time continuum on its way back to the 21st Century.
For the time being Nicole-458 is trapped in the 21st century; guarding Nassau Station's secrets with all but lethal force (she realizes killing someone in the past could have dire consequences), waiting for the "bubble" to collapse and hopefully returning her to the year 2552.
