Adaliz Dayan (SEY 2279 - 2317?) was a terraforming engineer who is credited with the discovery of the Banshee system. While working for the group terraforming Hyperion (Fora III) in the Fora system, she formed the Immram Association, an organization devoted to exploring the region between terraforming tasks.
Dayan disappeared under unusual circumstances while investigating a pocket of radiation. During the search for her ship, it was discovered that the pocket of radiation marked a jump point to the Banshee system. While it is believed she likely jumped there, she has never been located. The system was named Banshee in her honor, inspired by the nickname she earned playing college sataball.
