I got to thinking about this recently and I like the idea of Din encountering a group of self-proclaimed Mandalorians. I can see him going to Dathomir for a bounty and after being hurt he's rescued by a strange tribe consisting of both night sisters and brothers who not only practice their magic but have embrace the creed of Mandalor with Din finding out a group of Maul loyalists at one point were stranded on Dathomir and chose to raise a large number of orphans they came across while establishing a settlement.

I like this idea because I wonder whether he'd acknowledge such a group as Mandalorian as well as the other. I mean I feel like if said group was raised under the creed than they'd absolutely have a right to be called Mandalorian even if their customs differed. Regardless I do feel this would be a good plot for an episode or even a two-part event.
