The Dark Saber and the Dark Saber

The first mandalurian jedi was born to house visla with notable natural ability in the force he was tarah visla though at the time there was no house visla. If you're guessing that the parallel to the dark saber is the sword blackfire you are also correct give yourself a double pat on the back if you did that why wastarah visla the first mandalirian jedi? It doesn't really make sense that in thousands of years there would have been no other mandalurians with force sensitivity but it's part of their cultural belief that if you rescue a young child and you should you're responsible for them period.
