Ziv

 was an assistant of Garundel, and tracked the payments of deposits for his upcoming auction. Garundel liked her as she had the same ideals as he did, as she didn't mind selling the weapons of mass destruction. She worked the reception and took all the arms of the auctioneers. She thought the Sontarans all looked alike.

Ziv presented all of the items in the lot. She later took off the spaceship that hold the weapons. She wanted to take the money from Garundel's account and also wanted to sell the Doctor's TARDIS. She later wanted to travel with the Doctor at Will Arrowsmith's request, but Garundel murdered her before she had the chance; Elizabeth Klein lied to Will to spare his feelings.
