Mando'alor - The Jetii

Jedi Master Obi-Wan Kenobi, the perfect Jedi, sworn to his oath to the Jedi Code. Sith Slayer, The Negotiator. Blue eyes. Blue lightsaber. Master to the Chosen One.

Satine Kryze, Dutchess of Manda'yaim, pacifist leader of the New Mando'ad. The new proclaimed Mando'alor.

Rumours between the two flutter for as early as the Jedi Master being a Padawan. For when trouble comes to the Dutchess, the Jedi Master follows defending her from all harm.

The Darksaber, a lightsaber black with lack of colour, but with flecks of blinding white colour - a halo surrounding the blade. Flat and to a point, it's more of a sword than a lightsaber in design. It is made from an artificial crystal formed by a Jedi of Mandalorian ancestry.
While this blade sits comfortably in the hands of the Death Watch Leader, Darth Maul, the sabres true master is the Duke and Duchess of Manda'yaim.

Only, the Dutchess is no force user and has no one else ruling beside her. No Duke, force user or not, to call upon the blades meaning.
