TAW 5 History: Emeralda was one of the middle created Next-Generation Dragoons. Rather naive and innocent in most regards, she was brought into Cheryl Mizukazi's unit when Cheryl discovered her being abused by General Steel's men. She was in that unit as a guard who's exceptional speed was used for protection/guard duty, and the men thought they could get away with abuse to her. Bringing her in and paying her out of her own pocket, Cheryl gave her a new life, and gave her the job of protecting the teleporter to the PAX. While she sometimes goes out on missions, for the most part Emeralda is typically found on base.

Emeralda sometimes aids in the Kitsune Udon missions with her speed, along with NGD Curali, but spends most of her time learning about the world at Cheryl's request while on duty, reading books and trying to find out what she wants to do when her time serving in the military is over. Having begun dating Johnathan Hale over the last year, the two became engaged and became married after Hale seemed to put aside his playboy ways for her, falling in love for the young NGD. As they worked together and grew closer, they soon had kids as the long war with the Others and Order waged on, and Hale rose up in the ranks with his wife's help. Their children seemed to gain the speed from their mother and their father's wit and charm.

Now that the Others' are defeated, and the fact that there may be a new reality threat, Hale has stayed on with Peter and Em works as a lower rank officer so she can watch the kids for them, who seem to have joined Taiga's club. Em has matured greatly over the years and could likely raise in the ranks, having gotten a lot of confidence and experience from Hale, but seems content with her low rank due to the freedom it gives.

TAW 6 History: Emeralda continued to work for Cheryl and honed her skills and leading into The Alien Wars 6, Emeralda had raised in the ranks was very well respected in the military. When Hale became a Senator she put her career on hold to support Hale, but he was replaced by shapeshifters and did everthing in her power to rescue him. She eventually did and Hale went on to become a great Senator, but as sadly a one term Senator.

*Recently she was infected with the Dragoon Virus Mark III, a strain of the original Virus that attacked the Dragoons from The Alien Wars 4: Viral Exodus, along with Zephyr and a few others. It seems the virus was designed to no longer kill Dragoons but to affect their powers. She has showed no signs of her powers being affected but she is being careful nonetheless, even as the second Dark War looms and has opted to join the fight.
