The ones who play the Minis of Starwars, must know about the NIGHTSISTER Sith Witch, an Empire faction Sith, who was an early design of Darth Maul...

In each expansion of the game since Clone Strike, has been a "Generic" Sith:

DARK SIDE ACCOLYTE

DARK SIDE ADEPT

DARK SIDE MARAUDER

NIGHTSISTER SITH WITCH


Where and when these Siths come from?

My supposes are:

The Dark Side Accolyte is an eary design of Assaj.

The DS Adept is no other than a young Mara Jade.

The Dark Side Marauder come from the KOTOR Saga


Each of the Sith Minis come with force powers... but the intersting thing about the Witch, is the SITH LIGHTNING, to be just a generic uncommon figure, it's packaged with serious troubles... more than you can imagine if teamed up with Emperor Palpatine from RS (Pawn of the Dark Side ability)

There is more than just A MASTER and an APPRENTICE
