Small question about gobo root:
The description says that "Gobo is one of the few documented indigenous plants yet found." My question is: how would people know, ICly, what plants are indigenous and what plants are imports? Given the lack of good records about life outside of Yliakum, I'm curious about how they would know that gobo was native and yarrow wasn't.
Also, it seems kind of weird for Yliakum to apparently have few indigenous plant species. Are all of the animals also imports? I don't think you'd really be able to have the animals be indigenous but not the plants, as that sort of thing doesn't happen without catastrophic environmental damage, species going extinct, food chains disrupted, cats and dogs living together, etc.
