Regarding all of the strange races we see Travelers appear as.....

Is there lore to it? Did they chose that form because that is what some race looked like that they have visited in the past?
I'm not complaining FYI of only having 3 races. But when I was first playing the game (I did so without looking anything up beforehand), I would see these weird travelers in the space stations and think "Man, I can't wait to meet that species". But it never happened
So I'm curious if there is lore for these other "Races".
FYI, this is not a demand to have more races put in. just curiousity.

They are from basically the NMS multiverse. That's why they are described as being transparent in the dialogue. Some even speak like they come from a medieval times and they use a multi-sword....... I want a multi-sword...

I think what happens is that as you warp, your head starts to look weird, and after a few 10,000-100,000+ warps, well, that's the result.

Not even going to spoiler this anymore.

They're remnants of past universe iterations. Hell, there's story evidence that they may be remnants of past iterations of YOU, the current Traveler. As The Atlas has iterated upon the simulation, things have changed. Boundary failures record that the sentinels have expunged entire races until the core simulation was reduced to the extant 3 races and sentinel activity broke away from governance by The Atlas long ago, The Anomaly itself is at least partially an aberration that is only lets say half-initialized in each iteration, so it's easy to guess that there is significant drift between iteration initializations.

They could be past races that no longer exist (one of the Anomaly iterations hint at this in their introductory dialogue). They could be aberrations caused by code drift. We don't know for certain, but that's part of the meta-lore of the game: it's likely that we're intended to draw our own conclusions.

The conclusion I usually draw is that your PC was the best representation the Atlas could muster of its creator. I'm not sure that the travelers are necessarily mass produced other "races" so much as iterations of past test subjects. It's tried everything else once or twice, let's give daddy a whirl, maybe they'll be helpful to stave off annihilation.

Telemon complains a bit about how no matter how many races the Atlas starts a simulation with, it always ends up with the same three by the end. It sees this as one more sign of the Atlas's rampancy. And these three races never reference any others, but somehow they all know what a traveler is and are compelled to help them. That speaks to me more like the Atlas usually just says: "Here's a new weirdo, let's see what happens when this combination ends up in simulation..."
