The Trayus Academy was an ancient Sith academy located on the planet Malachor V. The Jedi Knight Revan discovered the abandoned structure during the Mandalorian Wars. The buried relics of Sith civilization that he uncovered there paved the way for his fall to the dark side and inspired his attempt to conquer the Galactic Republic during the Jedi Civil War. After Darth Revan's forces were defeated in that conflict, the Academy continued to serve as the headquarters of the Sith Triumvirate and the training ground for the Sith Assassins until Malachor V was destroyed in 3,951 BBY. Darth Revan made Sith assasins here. When they captured a Jedi they took him/her to Trayus Academy on Malachor V to corrupt the Jedi so he/her became a Dark Jedi and so Revans Empire grew even stronger.
