The Empire has fallen and a New Republic is born out of the conflict. But in the ashes of civil war, yet another life stirs...
After the fall of the Empire, Luke Skywalker began to instruct new students in the ways of the Force in the temples of Yavin 4. However, the Imperial Remnant and its various splinter factions also attempted on several occasions to instruct (or in some cases create) their own legions of Dark Jedi. Jedi Master Kyle Katarn and his apprentice were instrumental in curbing one of these attempts but when two of Luke's fallen students came together with a faction of the Imperial Remnant, they began what was known as the Shadow Academy.
It was here that force potentials were tortured and brainwashed using ancient Sith and Nightsister techniques until they were twisted to the will of their master Brakiss. These monsters of the Dark Side were called the Shadow Knights and although they were not true Sith, their strength was considered a tremendous threat...a strength possibly even equal to the Jedi Praxeum on Yavin 4.
In-game these units will behave just like the heroes but will do less damage. They will also only have one special ability, which will be more basic than their hero counterparts. The saber and skin variations will also have a limited randomization when they spawn.
