After or shortly prior to the Eros incident, Umea was approached Jules-Pierre Mao and his corporation to enlist in Project Caliban, a project which sought the creation of enhanced superhuman soldiers by combining the DNA of humans with that of the protomolecule. The project was ultimately successful and resulted in the creation of several super-soldiers, which the Martian government found efficient enough to invest in the project.
In "Here There Be Dragons", Umea is seen in a flashback, where she was accompanying dr. Strickland and Mei to the project's hidden laboratory. Having arrived there, Mei was placed on a vertical bed, presumably being thereafter injected with samples of the protomolecule by Umea.
In the present, she and her staff were ambushed by Holden and his crew along with Prax. When he spotted Mei's backpack, he enragedly took a shot at one of the staff members, resulting in a gunfight which Umea was able to escape, supposedly traping the Roci crew inside the room. However, they were able to break out and found Umea lying in a pool of blood, having been attacked by a human-protomolecule hybrid. She requested the help of Holden's crew, the latter of which refused to aid her. Defiant even when faced with death, she did not reveal any major information regarding the project, affirming only that "there is more where that came from".
