- "The children? Visser Three had made Darwin a host. Darwin, my son, was lost to me. But what about Madra? Was she still free? Could I... No. I couldn't. Someday, not yet. But someday she would know me. I would tell her all about me, all about who I was, how she had come to exist. And she would love me, as a daughter loves a mother. And if not, then I could always infest Madra, place some well-trained Yeerk in her head. Then she would love me. She’d have no choice."

- "I was in a bed. A narrow bed. I wore a simple pink robe. It was drenched with sweat. My hair was plastered down. My face was red from the strain of the previous four hours. Essam/Hildy leaned over the bed, smiling. I smiled up at him, but only briefly. Then, I looked back down at the two very small faces. The boy, my son, had not opened his eyes, yet. But the girl, my daughter, blinked and looked up at me, her mind perfectly empty, receiving its first images. Images of me. Mother. Mommy. Allison Kim. And a Yeerk named Edriss."
- ―Edriss 562
Shortly after arriving to Earth in the early 1990s, Edriss 562 and Essam 293 took two human hosts – Allison Kim and Hildy Gervais. Over time, Allison became attracted to Hildy, which Hildy reciprocated, with Edriss and Essam beginning to fall in love with the other as well. The four then conceived two children together, with Edriss/Allison giving birth to twins, a son named Darwin and a daughter named Madra.
The four parents loved and cared for their children; however, Edriss 562 and Essam 293 faced a crisis when their scout ship's onboard Kandrona begin to fail. Edriss then contacted the Yeerk Empire, outlining her plan for the invasion of Earth and the creation of The Sharing, and received a new Kandrona generator. Edriss then informed Essam that they would have to kill their hosts, Allison Kim and Hildy Gervais, with whom they had formed a partnership with, notifying her husband that they would adopt their children using their new host bodies. Essam refused to kill Allison or Hildy, prompting Edriss to retrieve a Dracon beam and threaten to kill the children as well, reminding Essam that they were Yeerks and that she desired to become a full visser. Eager to protect her children, Allison resisted Edriss's control long enough for Essam to overpower her. Essam then forced Edriss to free Allison, placing Edriss within her alternate host, Lore David Altman, while Essam/Hildy fled with Allison and the children.
However, the children developed a fever, prompting Essam and Allison to bring them to a hospital. Edriss managed to locate her children's name on a hospital database and made her way there, where she encountered a dying Essam, starving from lack of Kandrona rays. As Essam began to flee from Hildy's body, Edriss prematurely pulled him out, ripping his body in two and causing the latter half to become fuse with Hildy's brain, rendering Hildy psychotic. Allison, who had witnessed the event, then fled the hospital, returning in a disguise. However, Edriss had foreseen her actions and killed her when she arrived. With Allison dead, Edriss left her children at the hospital, causing the twins to be declared abandoned and thereby put up for adoption. After eliminating Lore as well, Edriss took on a new host, Eva. In order to avoid Eva's pity should she discover Edriss was a mother as well, Edriss took on other hosts and observed her children in secret, although, after leaving Earth and faking Eva's death, she lost track of her children.
- Edriss 562 remarks that Darwin was nine years old during the trial; Darwin and Madra are twins, who were conceived and born within the year Edriss had arrived on Earth (during the combat phase of Operation Desert Storm, January-February 1991), which would place their birth around late 1991 at the earliest. For Darwin to be nine, this would mean that VISSER takes place during mid-to-late 2000; however, based on the timeline provided in The Answer in conjunction with the books released pre-VISSER, the trial took place sometime around mid-to-late 1999, meaning that Darwin, and by extension Madra, would not be nine years old at the time, but rather eight years old.
