He is a SITH LORD. Oh noes!
Back in the day when he was young....well it was so long ago. Perhaps even a couple of lifetimes ago. No one mourns a forgotten childhood. Least of all this one.
For Kaan it began as a Jedi, distant relative to an ancient Sith Lord. He was always gifted in the force. He had another name once, Before he took the name of "Archon". He once told a fellow Jedi that the Dark Lord Kaan himself had whispered the name to him in a dream.
It meant "Prime"
He sacrificed her and drained her soul in his first alchemical experiment
Upon arrival on Korriban he was taken under the wing of the Dark Sith Order and trained by Emryc Nethalan. The Dreamking. Emryc tried his best to break the young Sith. Only to see Archon survive every ordeal and grow stronger from it.
He ended his training deep within the tomb of Marka Ragnos, where he recieved the mark of the Dark Lords by the spirit of Marka Ragnos itself. He was also infected by the same spirit and it tried to take over his body and mind.
Upon his knighting, he recieved from Emryc the Mark of Darkness took upon the Sith name of Darth Ragnos.
Archon Kaan sits on the Dark Council. Ringing true the prophecy echoed by Marka Ragnos. He is an unknown power on the Council. Preferring to stick to his alchemical creations and cults, rather than meddle in politiking. Which mirrors in his decision to stick with the Pillar of Knowledge. He usually shows great faith in the Council. And it is only when the hold of the Sith weakens that Archon Kaan chooses to disappear. Preferring to bide his time and wait for the Sith return to their glory rather than seek out active change.
Some might call it cowardice, but this aversion to active change stems from his inherent revulsion to Order. If Archon Kaan acts. The results usually are unpredicatble.
He is bound and sworn to Chaos.
