Yeah, and that doesn't change the fact that the armor design matches a race not present at Twilight gap and the word "Garrison" is both extremely relatable to that race and unrelated to the Fallen in any way. It's also worth noting that the description isn't any less fitting even if I am correct; my train of thought suggests it's the first mission of TTK that somehow drops this, and then what would make a description about beginnings unfitting?
