Dying in Chargen
@dragoner, interesting post.
I have never used the official Traveller aliens in play. In our current game all the PCs are human, which was a stipulated parameter at the start of the game. There has always been a premise that there may be aliens "out there", ruins of ancient civilisations, etc, but they are not widely known about and certainly are not integrated into a galactic civilisation in official Traveller or Star wars/Star Trek way.
The PCs (and their players) first got evidence of the existence of aliens at the end of the fourth session, when a DNA scan of the residents of the bioweapon virus planet revealed that they did not have fully human DNA. Since then there have been hints of alien technology (eg teleporters) on another world, and the current Annic Nova situation involves a genuine alien vessel with alien inhabitants. How that fits into the bigger picture of the universe and its timeline etc hasn't come out, though I have some thoughts about it.
In our campaign there is psionics, and a few sessions ago (which is over a year ago, as this is only one of several active campaigns for my group) the PCs found a branch of the Psionics Institute and a number of them underwent training. This is linked into the "ancient technologies"/"aliens" theme, which has been reinforced by my version of Annic Nova, but again the details haven't yet emerged.
I've never used a psion "class"/career path and don't know the details of the Zhodani (just the general idea that they're psionically-oriented humans with mechanical options for starting with psionics). Your objection to teleporting squads of commandos seems sensible to me!
I think my thing is that if we are going to do furries, do furries, it is just not my thing. Though I did see a furry artist, T5 person doing some trippy stuff with the Vargr on the discord. I've done weird stuff, like importing drow over 10 years ago, since the Darrians are just space elves so lets have the weird ones as well to use all the cool art there is for them, probably not my best idea, and I have moved on. Psions too are fine, it is just when all this gets added to the official materials, it lessens their utility to a non-official homebrew setting.
Your setting looks fun, and that is the best thing about Traveller is the ability to use the system to create an individual setting. Also it keeps grognards who know everything about the OTU from arguing edge cases, or criticizing the GM for not being faithful to the original material.
