They're missing for _Lost Russians_ and _Who Counts_
Now, for the Russians, I can bring in the Germans, or I could bring in an Executioner of the Alliance chasing Eldon, and with a really bad attitude about getting marrooned. Or I can just bring in some extra problems with settling on an unexplored world. How about Mammoths? Woolly Rhinocerouses? Dire Wolves and Saber Toothed cats? And an Ice Age style winter?
How about _Who Counts_? Do I need something relevant to Ruin's past, or perhaps those guys at the pickup bar were very bad types and holding a grudge?
