AB-343 was a lab that was operated by the Czerka Corporation. It was captured by the Galactic Republic early on in the Jedi Civil War and was left in ruins. After the Czerka technician Joni Ree defected to the Republic, she traveled to the lab along with three Republic troops, to try and access secure data files that were kept in the lab's computer system. However, they were attacked there by a Sith assassination team.
