I've got aliens as neighbors right next to Sol.
Political relations are friendly with trade and geo. data sharing.
They seem perfectly content with staying on their home world, since they don't have any ships or anything else beyond, so I guess they're non-TN.
Two questions:
1) Will they start building ships if I share tech data?
2) Since I'm friendly with them, will they get peeved if I start colonizing and mining their system?
