The Imperial worlds were well defended, better than most, but when monsters began to fill the streets of Ossus every man, woman and child were as scared as they would be any other planet, for they lacked the bastion of light that usually appeared in any other planet when the Exalted arrived: They lacked jedi. And when the best answer against the exalted is nowhere to be found as a result of war-mongering, even a planet as well defended as Ossus would be fighting an uphill battle. The price of denying all the force users, the price of not submitting to Darth Raze.
Yet, despite that and the fact that so far attacks from the Exalted were aimed towards the Core, they were not to be underestimated. So far the other planets that had fallen had been fighting them on their own, but Ossus had the might of a planet spanning empire, even if the Empire had yet to fully recover from their past wars. That's why Gareth, the firstborn of the Exalted, had tried his best to contain the beast within in, to not let it go on a rampage and kill everything that stood in his path alongside the rest of his brothers and sisters. No, he needed to have a clearer mind.
Wielding his Matukai gauntlets and his old White Lion armor, the man walked forward as many beasts charged ahead, letting them enjoy the carnage and spread throughout the planet while herding them towards estrategic areas, being the only one with any authority over them other than their father and leader. Although he looked human, people would still be able to recognize him as the monster that gloated over the tragedies on both Coruscant and Mon Cal years ago. Everyone would learn that no one was safe from the White Lion.
