She gained custody of Jeremy and Corey in 2367 after Jeremy's guardians and Corey's parents, Lee and Amy Aster were killed aboard the USS Melbourne at the Battle of Wolf 359. At that time, she lived in Shorewood outside of Chicago. (Star Trek: Hidden Frontier; Star Trek: The Cantabrian Expeditions: "Dream a Little Dream of Me")
Helen Aster strongly believed Corey would "grow out" of his paranormal mental abilities, and insisted Starfleet counselors create a mind block to stop his powers from developing. (Star Trek: The Cantabrian Expeditions: "Dream a Little Dream of Me")
- Helen Aster's name comes from a post on the Hidden Frontier forums by the actor portraying Corey Aster, J.T. Tepnapa, when asked to "flesh out" his family.
