Arnora

Arnora was mother superior of the Unon.

After the Last Great Time War, Arnora and the Unon became time and space's "judge, jury and executioner". She led a crusade against the Lect for that cause.

She trapped the Ninth Doctor in a sub-dimensional void after he tried to summon the Unon for answers. Whilst there, she probed his mind to discover how he survived the Last Great Time War, but eventually gave up. She tricked the Doctor into being brought to the planet Traxis to heal a time fissure. When this was done, Rose Tyler tricked the Doctor into revealing the location of the Unon's Perpetual City, and had him brought aboard the Lect command ship. With the Doctor's help, the Lect Prelon Marleth turned the Unon's entropy engine on itself, and Marleth and Arnora destroyed one another. (COMIC: Weapons of Past Destruction)
