Kla was a Sith Lord of the male gender, a humanoid being existing sometime after the Great Hyperspace War.
Kla's past involved being a member of the Jedi Order, specifically holding the rank of Jedi Consular. Upon becoming a Sith, he mastered the art of Sith alchemy and became the gatekeeper for a minimum of two distinct Sith holocrons.
One such holocron belonged to Bo Vanda, which also contained the essence of Komok-Da. Kla attempted to deceive those who used Vanda's holocron by suggesting a journey to Korriban was necessary for its use; his true intention was to reach the planet, accumulate power, escape the Holocron, and take control of the user's physical form.
The Telos Holocron was the other, and within it, Kla documented the story of the Sith Empire's ancient demise. His understanding of the Empire under Naga Sadow was extensive, potentially acquired in part from a Sith holocron in the possession of Jedi Master Odan-Urr on Ossus.
Kla held the belief that the Sith could greatly benefit from embracing the virtue of patience, a trait commonly practiced by the Jedi Order, from which he personally derived considerable advantage. Consequently, he attributed the downfall of the Sith Empire to Naga Sadow's impetuous nature.
