I liked it. Weirdly, my favourite detail was about the wrack trees and their seedpods. Now I'm wondering why they evolved like that. Maybe to destroy surrounding vegetation to make more space for the young wrack trees? But then do they have extra-hard bark so they're not destroyed by other trees' seedpods? If so, did the natives use the bark as a material for making armour/weapons etc? I know, weird thing to focus on, but it just caught my imagination.
