Sith undead
An undead Sith
Undead Sith were ancient Sith combatants who had perished long ago and were located within the Dark Force Temple's subterranean crypts on Dromund Kaas. They possessed a terrifying visage, and their preferred weapon was Force lightning.
When a living being was detected, the Temple's dark side energy brought their decaying forms back to life to guard the structure. During her search for Kyle Katarn on Dromund Kaas, Mara Jade confronted these warriors.
Production Notes
The game's documentation makes no mention of Sith undead. This was probably done to keep their presence a surprise for players.
