"Darth Demacia" is a human-jawa hybrid living in the desert wilds of Tatooine. Fiercely proud of her Jawa heritage and strong with the force, Demacia turned to the dark side and became a Sith apprentice when she became conflicted about her human side. She eventually overpowered and killed her master to persue her own path. She is occasionally seen at the Mos Eisley spaceport and maintains a little-known Jawa stronghold in the deep desert. Her darkside powers are likely the reason why the location remains a mystery and why the Jawas and Tusken Raiders continue to maintain their uneasy peace.
No, none of this is canon and it doesn't have to be. That's not the droid I was looking for.
