"We've lost contact with Project Quell, in the lower ground labs. It's, um, supposed to study those rakghoul creatures. They kept a whole pack of them there. The scientists wanted to study the rakghouls' behavior, try to find weaknesses we could use."

Project Quell was a Galactic Republic research project on the planet Taris that studied the behavior of rakghouls. Doctor Zalaren was a scientist on the project, and was the only survivor when the rakghouls broke loose in the research lab and attacked the scientists.
