Sierra-331 Isara

Spartan-B331, only known as Petty Officer Isara, is a young girl, age 20, with dark-blue hair and eyes and a very kind personality. She has fought through the campaigns, ranging from Reach up to the free Principality-planet of Gallia, a small agricultural planet and an ONI HQ in that region of space. She is a specialized engineer and tank driver. She also tended to wear a shoal, saying it was 'for good luck in the face of hell'

Reach to Earth
In the first skirmishes on Reach, she and Omega team fought together to fend of a siege on a weapons facility in the east, where Omega had lost their team leader. Isara was reassigned as their CO and then New Alexandria followed as their target. Under heavy barrage from Plasma Mortars, the team had to fall back through the underground tunnels, where they briefly met up with Team Noble, who had just lost their second soldier. Isara and Omega fended off an Elite squad, then Rendezvoused with an evacuation Pelican.

Extract from communique with UNSC HQ

''Holland:This is Holland. What's your status, Omega?''

Isara:We're pulling out now, sir. Just encountered Noble down in the tunnels.

''Holland:Understood, Petty Officer. What was Noble's status? I couldn't get through.''

''Isara:Noble Two is down, sir. Shot through the helmet by a needle rifle, from what Noble told us. Five is actually MIA.''

*Utter silence*

Isara:Sir?

''Holland:Understood, Petty Officer... You and Omega are to head for the UNSC Voyager. Your next priority is to return to Earth and set up positions there. How copy, over?''

''Isara:Loud and clear... Omega Actual out.''
