Looks like I’m back to the main quest by accident, after wondering around Hyrule for “years” (in the game time).
Today I just helped Riju defeating the attack from Gibdos. By talking with her in the shelter I just realized that this was part of the “ Regional Phenomena”, which I deliberately tried to avoid in the game.
Not sure if anyone is like me, who enjoys doing side quests more than following the main story. Let me fight more pirates and help Koroks unite!
