Darth Merphis the Forcewalker

Title:
Dark Council member, Master of the Sphere of Ancient Knowledge
Heir of Tulak Hord and Kallig
The Great Prophet (worshiped by the Cult of the Screaming Blade)

Appearance:
Very little is known about her true physical appearance. Since she always appears cloaked and veiled, only the most basic characterizations can be used to describe her. What is known is that she is a humanoid female of above average height, with a lean musculature. Her race and species are unknown, as well as any finer details regarding hair color, eye color, etc. The reason behind her constant concealment are unknown.

Bio:
Much of her early history has been erased, most assume deliberately. Her earliest record doesn't appear until she was already Lord Zash's apprentice in Korriban and soon took over her former master's position. Any records prior to this no longer exist. During this period, she took in Ashara, Xalek, and Archassein (who was originally Darth Baras' apprentice) under her wings. She was eventually granted a seat in the Dark Council after defeating Darth Thanaton in "an honourable Kaggath duel" (Details are top confidential and only accessible to certain dark council members), along with a new title given by Darth Marr.

Personality:
Pragmatic. Calculative. Enigmatic. Compared to her fellow Siths, she prefers to channel her fury, passion, or lust towards a specific person or goal in a somewhat controlled manner, rather than unleashing them mindlessly. Although it comes at a price, her ability to plan and act logically gives her a keen advantage over those ruled solely by their emotions.

Power and Ability:
Force walk, a forbidden and lost dark art to bind a Force ghost and take their power. (Bounded ghosts including Lord Ergast, Darth Andru, Kalatosh Zavros, Horak-Mul, and Mar-Da. However, it was only because of an ancient Rakata Mother Machine and Voss healing ritual that her body and mind was recreated so that she could withstand the physical strain of using the ghosts)

Rumours:
She was seen to be very intimate with a decorated Imperial Captain Malavai Quinn that serves Darth Archassein (to a level that made people believe they would soon be engaged) but at certain point they stopped interactions for good.
