I figured we need some more antagonists in this, as well as at least one actual Sith character
Name: Darth Pestilus
Species: Human or possibly a near-human species (noone is quite sure)
Sexual Orientation: Unknown
Affiliation: New Galactic Empire, Sith Order
Title: Dark Lord of the Sith
Weapon: Single-bladed lightsaber (red), he also plays on fear to demoralise his foes
Description: He hides behind a long black cloak obscuring most of his face in shadow, though his eyes appear to glow through it.
Backstory: How he eluded the Jedi and the Republic for so long remains a mystery, however, it is widely suspected that he had a hand in the bio-weapon used against the Republic Star Destroyer Cygnus
. He is also known to use his enemy's fears and anxieties against them.
