Revan walked the surface of the graveyard world, feeling the power of the Dark Side coursing through him, a black tidal wave of annihilation, the power to destroy. Revan knew that destruction was only half of creation and used his strategic mind to eliminate those that opposed him in his vision of uniting the galaxy against the greater threat of the Sith Emperor upon Dromund Kaas.
Here, having established his Sith Academy, was only one of many simultaneous strategies he would employ to bring about the ultimate destruction of the Sith Empire.
Revan's fall began with pride, with self righteousness, much the same as other great fallen Jedi, such as Exar Kun.
He searched the tombs of the ancient Sith for holocrons and other artefacts of dark power to aid him in his quest. The Valley of the Dark Lords called to him with phantom voices, for even the fallen Sith still yearned for power and to exert their will.
