Mange had just left Yavin IV in hi master's infiltrator without alearting his presence to the jedi. They would pay. Those Jedi would pay for what they did to Lord Hethrir and Jeng Droga. Mange had looked up to Hethrir, he had made Mange as strong as he is today. Just before he had left Yavin, Mange had removed the steel fangs he had made as gift to his master from Hethrir's lifeless mouth. He had place them on a necklace he had made even though Hethrir's canines where still inside the fangs. Mange also consumed his master's blood; he felt as circulated though his body that it had given him a new strength. He kept Hethrir's light saber even though he probably never use it, just keep it in remebrence of the pain, suffering, and power it had delt him.
The Jedi had crossed the line. All of them would parish in agony. They started this war, they don't know what they have done.
Mange had to seek out Dorn Tlo, the fallen Jeng Droga's apprentice. He knew is hate for these Jedi had grown too. He would need his help, along with all the sith.
He set his course, making sure to avoid all planets' and fleets' sensors.
