It really needs NPC's. I don't want it to turn into a dungeon crawl, so when I run it I'm adding a character:
Dr. Zbigview 67ACD6 Scholar
Archeology-5, Survival-2, Laser rifle-2, ATV-1, Liason-1
The doctor is like the "Daniel" character from SG-1, and he is _convinced_ that some Landian hieroglyphs depict flying saucers and Droyne. He can be encountered at castle alpha, doing "research". He will ad humor and zest and conspiracy.
People like him are why the planet was red-zoned in the first place....
Add some artifact smugglers, some street-life, a bored but determined cop, I dunno, it just needs NPC's. I'm also adding religious fanatics because I'm going to run "Reliquary" based on this planet.
