Kindness for kindness! So your people can theoretically remain outside of their land for so long as they have Harkti leaves to filter oxygen? I'm assuming any oxygen-breathing species would find it tough to live in your land because of that; any diplomatic meetings would probably need to be done just outside your land where Harkti bushes aren't in large concentration.

Exactly! That really is the only major hurdle for them, and it's one they are willing to accept when it comes to making friends, afterall they are hardly able to host visitors in their lands. I was thinking that perhaps they could be trading something like cultural knowledge in exchange for finished goods, in that they are more than happy to provide the worked products of their land in exchange for knowing more about your nation.
