CZ-94, a droid working within the portmaster's office located at the Serenno Spaceport, met its end at the hands of Asajj Ventress. Ventress, the Sith apprentice of Dooku, came to the spaceport searching for Jenza, the sister of her master.
The audiobook Dooku: Jedi Lost, penned by Cavan Scott and released in 2019, included the initial reference to CZ-94.
