Chaf'ees'aklaio, or Feesa as she was known by her core name, belonged to the Chaf family. In addition, she held the position of second niece and aide to Aristocra Chaf'orm'bintrano, whose core name was "Formbi". She accompanied the Aristocra on the Chiss ship Chaf Envoy, which transported Luke Skywalker and Mara Jade Skywalker to Outbound Flight, a Galactic Republic ship that had met its end in the Redoubt, a nebula serving as the final protective barrier for the Chiss.
During the expedition, she displayed valor and sustained injuries from the Vagaari upon their emergence. Furthermore, she played a key role in executing some of Formbi's strategies to deceive the Vagaari, paving the way for the Chiss to launch their attack.
