As I have stated before, the majority of them are guaranteed to die. Current estimates predict the population to fall well under 100 billion after the colonization efforts not including anyone lost to warfare or major catastrophes.
Also, the template I used was copied directly from the website. Is this template not up to date? If so, someone should probably fix it straight away so this doesn't happen to other new users or new faction leaders.
The leaders and currency are a WIP. I usually edit things on my computer before uploading them to the wiki. Thusly; they are not yet on the wiki but they are being built. Using a word editor is simply easier and doesn't screw me over if I lose connection.
The language they use is not present in SA. This is a plot point in the RP thread which I have linked a few times now. Through RP they will learn the trade languages here. They speak a language they call Galactic Common which is a multitude of languages crammed together primarily consisting of English, German, Russian, Chinese, Spanish and a few other minor languages (Farcy, Paashtun, etc).
As for the currency, this is a WIP. It'll probably be done today.
I am aware of the size of their military being small. This relates to the plot. They didn't intend to come to this universe. Thusly, they didn't send an entire battle group. They sent an escort fleet which isn't made to go to war. It's made to fight off pirates and raiders; whom in their universe usually can't fight an escort fleet nor a battle group unless something has gone really wrong.
As for reaching out for help I am currently receiving assistance from Jack Pine, WillLi, Madi Harper, Dragon_God, Lavalung, Leonardo and a few others as well as anyone that wants to hold a conversation about it. This faction isn't made to upset the balance or be 'all powerful' while still being lore friendly to the parent universe upon their arrival. What I mean by that is that their escort fleet simply isn't going to come to 'let's send three ships' because that isn't how they fight or group their ships. These ships are large, true, but it's due to their cultural heritage and their manufacturing capabilities back home.
I'm fully willing and able to explain these upon request. Just reach out to me over discord.
