I noticed a place in skull island, where the Water Moles are, it's called Orchard Plateau. We never visit it by the main quest (I know because I finished it) so I wondered, what is the Orchard Plateau for?
My guess is K I is leaving room to add a new quest area at some point in the future. I read that in Wizard they wished they had made a few more usable door openings in a lot of places because of how much the game grew. In Pirate, they learned from that and have programmed more, that they can use to add new areas later. That's why there are so very many cave doors all over the place too. I, too, am looking forward to seeing what is up on that plateau.
It is nice to know what it is for. It's such a cool looking entry to an area, too bad those without Milo won't see it. I'm glad one of my lower level pirates has him. I'll be patient. I do like when our pirates are sent back to find cool new stuff in earlier areas we thought were done though.
