Well, the magical lagoon is where the fish came from and the garden is where the plants came from. Actually, one of the events that I encountered was that one of the magic fish was found and that it increased the tech catagory that it corresponded to. So, maybe there is also a "magic plant" event as well.
I'm also going to try out different strategies and time-trials, but mostly, I just want to know more about the island. I NEED CLOSURE!
