I Googled 501st Legion (sorry, didn’t watch Star Wars in childhood as it was not available where I grew up). But in general, be it the Marathon battle reenactment, or a knight tournament or something else, it is all the same. Bright people, very dedicated to their area of interests and… well, unusual. I knew some people who were making own costumes, they also had online stores where they’d sell “stuff for sensory people” before it became commonplace, so, bright.
If we are talking about the cost of the outfit, how much is it?
Also, I saw that they are invited to perform at hospitals, etc, so some $$$ ? Right? And there is a “trooper of the month”, so, not unlike Boy Scouts? There may be a lot of rivalry.
ETA. About the personalities. Not all are introverted. I'd say, "romantic". Here is an interesting story. A British jouster who was killed during a reenactment for TV. His wife, herself a reenactor, said he would not dream of a better death.
And I can imagine, people are people and may have issues, but I think this common shared obsession is a strong bond.
Paul Allen, 54. was not wearing his shield properly when he took part in the joust, an inquest heard today.
