Ayfai

From Tardis Wiki, the free Doctor Who reference

Ayfai was an Arldan who briefly travelled with the Eighth Doctor as his companion.

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)
