I recently made a character with a player (for that player) and having gone through a dark voyage and met xenos we wanted to decide which kind. As he didn't like those of the books and made one through the xeno generator (for Dark heresy but it works wonderfully for RT).

Thus was the Ranamapuraelians created. They look simmilar to the Kaminoans (and are of rougly the same size) but change colour depending on the season. They are greedy and hightech but wear little cloths (being fairly cold resistant) except during high heat when they wear special cooling suits. They are not very spiritual and prefer cash before gods. Their technology is based on fullerene ( http://en.wikipedia.org/wiki/Fullerene ) and they have invented, amongst other less relevant technologies, Superconductors, Warptravel, Electroflails and lasweaponry. Their armies are fully mechanised.

Their most common warship is the Far-range Covert Mega-Frigate which exchanges sheer firepower for a far superior range.

An Average Ranamapuraelian has the following stats: WS 22 BS 34 S 23 T 25 Ag 23 Int 45 Per 32 Wp 25 Fel 24

A Far-range Covert Mega-Frigate has the following stats and rules. Speed: 7 Manoverability: +17 Detection :+16 Hull Integrity: 48 Armour: 19 Turrent rating: 1 Weapons: 2 Dorsal Long-range Megalas ( Str 4, Damage D10+1, Range 15, Crit rating 4)

So I need help with fleshing them out and making them more intresting.

I think you need to ask yourself the question: What is keeping this race from trying to conquer the Koronos expanse? They have the capability with their voidships, they have advanced weaponry to rival the other races in the sector. So why do they content themselves to trading? Are they pacifists, are they a dying race, perhaps they just have the one planet or they are from another sector and now they check out the opposition before sending in theif fleets of conquest. Are they a threat to humanity or not?

Once you know their motivation, you can make them more interesting.

Yet it is numbers and risk evaluations that keeps them back. There aren't too many of them yet, they could possibly conquer a poorly defended planet but at too high a cost for it to be valuable. They have their homeworld and a few colonies (with more springing up at an alarming rate) but it is only their homeworld that can be considered properly ihabited yet as the others are more like stations that provide reaserch, vacation spots or reasources.

They are also weary of the technology of humans and other xenos, the Ranamapuraelians use mainly lasweaponry (being poor melee fighters by nature their Electroflails are more for intimidation and trading) and while their lasweapons are at least equal to human ones they are little compared to shuriken catapults or boltweapons. Their armies are as previously stated fully mechanised but they are still equipped almost solely with longrange lasweaponry, meaning boltweapons and meltas are a nightmare for them. They have high reasources to call upon would a war occur but starting one would be too high a risk for too small a gain (but hiring Kroot and human Privateers might fit their alley perfectly).

They are a potential threath to humanity but currently they would be blasted appart if a war occured.

They are motivated by worldly goods. Money, high value tech, anything expensive.

I''ve found that to make a xeno race more interesting is to start at the basics and from that, avoid the human analogue that WH40K and fairly much every other RPG tends to follow- humans with pointy ears, humans with green skin, humans with bitey teeth, slimey humans, human weeboos etc... two arms, two legs, 1 head and mostly the same amount of external organs.

If you avoid all that, grab a book on microscopy or deep sea animals and throw together a truly ugly alien bastard, then throw in some truly aberrant behaviour like eating their last-born young, urinating on house guests, common human mannerisms (like baring teeth when you smile) they find grossly offensive and virtually no identifiable facial expressions for people to figure out. Then you're kind of beginning to touch on what really is an alien life form and PC's don't really know how to deal with that crap.
