Captain Aeris was a Human and Stafleet officer in the late 24th and early 25th century. She served the U.S.S. Xena until it was destroyed in 2390, leading her to take command of the U.S.S. Zephyra, part of Task Force Zeta.

In 2406, she and many others were caught in a massive molecular reversion field which caused her and everyone in it to revert to a younger age. This caused everyone involved to temporarily lose years of memory, and in most cases, retake Starfleet Academy.

In 2410, she became Captain of the U.S.S. Viracocha, part of Star Fleet Battle Group Sigma. During all her commands, she was known to have a crew that was comprised mostly of females.
