So I just had an idea, talking to my mom (Foxy Moxy). So what if the next feat unlocked an underwater region...that was highly quest related. This region was imagined by Zille, but she imagined it too hard and it sank.
In this region, we learn that Zille actually imagined 2 regions, but after this one sank, the second one was forgotten and disappeared. So we all must do something in the underwater region to bring its sister region back.
What do you think of this?
