I once encountered this woman on Taur island in Waven, and what she said confirmed to me that we would get more islands and possibly nations in the future.
She mentions Sufokia in her little speech, which we all know is the island we saw in Season 2 when our beautiful iconic prince the prince of Sufokia tried taking it from Phaeris before Rushu barged in.
But yeah, anyway, the way she casually talks about Sufokia existing in Waven despite not even seeing an island for it is a sign that we'll get to see more islands in later updates.
Like I know the game is still kind of new since its history mode isn't even far yet, and we still have so much more to know, but I almost didn't think we were going to get any more islands since the game clearly shows us that the great wave was apparently so severe that even Ogrest's tears were nothing compared to it.
Maybe it's just me, but thinking that Waven would only have the islands we got right now almost made me complain.
Cuz how are you gonna have all this world-building only to give us a few islands??
I'm so relieved we'll get more islands later on cuz I was about to go insane going to the same places over and over again just to raise my levels.
