After defeating the Mandalorians they found out a force beyond the outer rim was influencing them. Being the heroes they were they went searching for it, and found a hidden Sith Empire led by Sith Emperor Vitiate. Vitiate twisted their minds and turned them to the dark side and then sent them on their quest to find the Star Forge.
