Nikkos Tyris

Nikkos Tyris was an Anzati Jedi Knight leading up to and during the Clone Wars. Some time during the Clone Wars, Tyris and at least two other Jedi discovered ancient Sith secrets. Tyris and his companions left turned to the Dark Side and formed the cult known as the Jensaarai, a Sith word meaning "hidden followers of truth. Tyris became the first leader of the Jensaarai, known as the Saarai-kaar.  The orriginal Jensaarai taught their Padawans Sith techniques, but were unable to turn them to the Dark Side.  Instead, they lead them to believe that the rest of the Jedi Order had gone over to the Dark Side.  Tyris established a base for the Jensaarai on the planet Susevfi.  Some time around the end of the Clone Wars three Jedi were sent to dispatch with the Jensaarai.  They were Nejaa Halcyon, Ylenic It'kla, and a Jedi Ylenic identified as "Desertwind", who may have actually been Obi-Wan Kenobi.  The three Jedi sqared off against Tyris and two of the other Jensaarai leaders.  "Desertwind" managed to kill his opponent, and Ylenic slew the Jensaarai he identified as "Dustrose". Halcyon, however, was less fortunate than the others. Tyris took advantage of Halcyon's lack of telekinetic powers and ran him through. However, before he died, Halcyon drained the energy out of Tyris's lightsaber and used it to break every bone in his body, killing him. The release of Dark Side energies at the deaths of the three Jensaarai leaders collapsed the structure where the rest of the Jensaarai were dwelling, killing the last of Dark Siders and leaving alive only the apprentices who still served the Light.
