>>109761684It's a bit disconcerting, especially when in the series they make it very clear they arrived AS UrSkeks but then became Mystic/Skeksis AFTER messing with the crystal.
But I have a theory.
Aughra only dealt with the Skeksis being in charge, ever. It's never explicity stated in what order of events things happened, so... I think the order of events that fits everything in a non loop-holy way is as follows.
>UrSkeks arrive>They're just meandering about. Meet Aughra. Cool bro. Other worlds. Aughra interested.>UrSkeks fiddle with Crystal, but they're not LORDS of it or anything. Just chill with it.>Woops, split personality disorder time. Mystic and Skeksis appear.>Mystics go fuck off to desert>Skeksis seem cool at first and enjoy themselves.>They want to fiddle with the crystal more without interruption>"Hey, Aughra, you like space yeah? Here's an Orrery">Skeksis take over>Mystics still sandpeople>Skeksis change history to make sure no one remembers mystics OR UrSkeks
