Lost Lore Found: Ancient Dahgee Jedi

OK, so I've been looking into old Star Wars lore that isn't touched upon, and I came across this: The Ancient Dahgee Jedi.

How far back into Star Wars history do these guys go? Where is this planet Dahgee these guys originate from? Why do their lightsabers look like that? We don't have any answers for that because they were just made for Star Wars: The Clone Wars: Adventure's costume shop!

But you know what? Screw it! I will put it upon myself to make lore in my fanfiction timeline for this mysterious sect of Jedi, their planet of origin, and their ridiculous-looking lightsaber blade design.

Seriously though, these lightsabers are the dumbest looking lightsabers I've ever seen, and that's what I love about them. They should be made canon.
