Ayfai was an Arldan who travelled with the Eighth Doctor.
At the age of forty, Ayfai was awaiting execution for political dissidence on Arklus. The Eighth Doctor broke her out of prison and took her to Cheldon Bonniface for safe haven.
While in Cheldon Bonniface, Ayfai helped the Doctor prevent Earth from being invaded by the Chelbil. (PROSE: Not in My Back Yard)
