The Decimator Laboratory functioned as a facility of the Galactic Republic located on Eredenn. Its purpose was to safeguard the control sequences essential for operating the Decimator weapon while it underwent evaluation. During the Clone Wars, specifically in the Battle of Eredenn, Sev'rance Tann captured this laboratory. Tann then absconded with a data droid from the facility, transporting it to Alaris Prime with the intention of completing the process of activating the Decimators for deployment by the Confederacy of Independent Systems.
