Ah'len was a Xyrillian engineer who came from the city of Thera. Her favorite food was dutara root. In 2151, Ah'len assisted Charles Tucker III in repairing the engines on her ship. She had a brief flirtation with Tucker. After the ship was repaired, Ah'len showed him Xyrillian holographic technology, recreating two different landscapes from her homeworld. While sitting in a holographic boat in an ocean, she and Tucker immersed their hands into a box of granules which began to glow, enabling them to read each other's minds, and transferring energy between the two. As it also transferred genetic information, this interaction with Ah'len caused Tucker to become pregnant.
