I noticed that all the NPC types are human (I'm assuming). I would throw in an alien or three.
Good point. Hmmm... [looks over the manifest]
We'll call the first ten as being human, either Vilani, Solomani, or mixed.
1. a Noble incognito
2. a Miserly Scout
3. a Sinzarmes Merchant in search of his ride
4. a women of questionable means
5. a army man doing the permanent change of station thing
6. a water farmer
7. a priestess
8. and her acolyte assistant
9. an extradited criminal
10. a unbalanced security team member [like the navy seal dude from "The Abyss"]
Now, 11 thru 14 we could turn into aliens...
11. a TAS Journalist [maybe a Bwap]
12. a stowaway[Could be a band groupie, OR, could be a Droyne Sport running off in the deathless state to do something the coyns predicted. Who knows, maybe both!]
13. a professor [will say a Darrian Professor]
14. a possibly contagious medical patient [Vargr with Rabies]
#15 is our MAD Kkree Technician [maybe. I'm rethinking that one].
Then we have 16 and 17. I had a idea about 17..
16. a Susag company drug rep, who has a stash of High Leaf, or some other substance [alien ideas?]
17. an engineering student [Sword Worlder...I'm thinking like the German model airplane guy
from the original "Flight of the Phoenix" movie]
18 and 19 are John and Jane Doe [Grotes!]
and that left 20 as open.
Hmmm.. How about a Saurian Noble travelling with a human psion [notional idea out of "Babylon 5", with the characters of G'Kar and Lyta Alexander]
