Hekas-ni was a Human Dark Lord of the Decreton Empire during the early history of the Sith Order of Decreto. He was also the father of Setal-ni, who later fought in the War of Twelve Heirs. Hekas-ni was responsible for the greatest expansion of the Order's power before the Legacy era.
Hekas-ni was a well respected, and greatly feared Dark Lord who brought the Sith Order of Decreto out of the squalor of its early years, and turned it into an affective fighting force, and a government to be feared by its enemies.
Hekas-ni died a natural death in 3,964 BBY, with his son declared as his heir. All did not go to plan, and war broke out between the members of the Sith Council, all of whom wanted control of the Empire. In the end, it was not Setal-ni who was the victor, but Sam Sinays.
