Biography
The son of a diplomat, Viron enrolled at the  at the age of nineteen after discovering his potency in the Force. Learning under Jedi Master Xanus Baran, Viron quickly rose to the rank of Jedi Knight, eventually taking an apprentice of his own in the Kuati Tasen Denon.

Shortly before the Glorian War, Viron and Denon were sent to on a recon mission. It was there that they encountered the mysterious Dark Jedi Order, who were working to undermine the Glorian infiltrators. At the behest of his old friend Mar Voran, who had since joined the Dark Jedi, Viron and Denon agreed to help the secret order.

After the Dark Jedi were disbanded, Viron and Denon did not return to the Jedi Order. While his apprentice departed for parts unknown, Viron fell into contact with Lysira Naris, another fellow Dark Jedi, who offered him a place in her new Sith Order. Viron accepted the offer and, taking on the name Darth Kallus, became one of twelve Sith Masters and selected the former slave Zashra Malincha as his apprentice.

When the apprentices betrayed their masters and fell in with Varon Krul, Lord Kallus was sent to Ossus to warn the Jedi. However, his warning came too little too late as shortly after arriving, the forces of Darth Taral attacked the Jedi Temple. During the ensuing battle, Kallus encountered his former apprentice Tasen Denon, who had since joined the Marked Ones, and was taken captive by the Sith.

Being held on the Mandalorian ship Awaud, Kallus ended up being taken to when the Marked Ones decided to abandon Taral to the Resistance. There, he was forcefully initiated into the cult along with fellow ex-Jedi Zarin Kal and Natia Dorn.
