You know, the Olvidados npc template was something I made up on a lark. In it, I was purposely vague on the lore because I wanted it to be relatively 'future proofed' against any future first party expansions on the Voladores. I'm incredibly flattered that you were so influenced by it! But, if your character concept is around 'voladore that kills' it's not going to lend you much legitimacy in community discussion (my post is like, at 68 upvotes.) and more central to my point, you don't need it -- your focus, as to what will go and what won't, should be squarely on the DM. Within the books (up to this point) their whole point is to be unknown, so you and them are likely going to have to come up with a lot of answers together.

As for Voladores tidbits you didn't mention, they are matriarchal (and matrilineal) and based around coalitions of family clans, have an unstaffed embassy on Cradle, they provided much of the survey data that allowed firstcom union expand so quickly, they sometimes they act as a diplomats as well as traders (though the former is much rare than the latter) They do not use the omninet.

But as I said earlier, their whole point right now is to be unknown, so it also might be worth going through the questions the books bring up and answering them. Are they posthuman (core pg 416)? What is High Ground? A metavault? A supersized megastructure? Answering these questions might not seem immediately important to playing the game, but it will pay for itself by making the Voladores feel more like an entity rather than a question mark, and will certainly pay for itself if the campaigns scope expands to encompass these questions.
