Dromard Pallax

Dromard Pallax is a member of the sith race and the founder of The Sith Eternal.
During the Great Hyperspace War in 5000 BBY, Dromard was the second in command to the Dark Lord of the Sith Naga Sadow. 
After the fall of the Sith Empire at the end of the war, Dromard and his forces chose to seek power on another galaxy, but his invasion was stopped by the Regenian Army. During the war he discovered that the Xegolite, a metal from the surface of the planet Exegol was capable of reflecting the Regenians´ strange force powers. Seeing that the only viable option for his troops was retreat, they hid under Exegol´s surface and formed the Sith Eternal cult. After this, Dromard chose to voluntarily place himself in suspended animation for thousands of years.
During his sleep, his followers´ descendants evolved after living underground for eons, finally becoming the new race known as the Sithikk.
