Aithne was a young fire witch, hiding among the people of Emerald City.

When it became known to the Wizard that Glinda is preparing an army of witches against him, he ordered all young girls from the city round up and tested by West. Aithne was chased by the Wizard's Guard to a dye shop where she used her magic to kill them all and torch the place. Calmed down by West, she got scared by the cage brought by the Wizard's Guard and tried to run again.

West trapped her in a pit with a forcefield keeping her and her fire magic in and the Wizard ordered to have his Council - spies for Glinda - thrown into the pit to spend all the girl's magic.

Exhausted and on the brink of death, Aithne was taken by West outside the city and killed in her sleep.
