Multiple characters say "You are that kid" to the MC, implying they know him. This suggests that he's clearly not from Earth and that his origin is tied to the Nine Realms. As for Vanny's vision, more will be revealed in later chapters. By the end of the story, the MC will stand atop the Nine Realms as the strongest.
YESS he will RULE ALL 9 REALMS CAN'T VERY VERY good gameTo me right now this is is newest and best game in my list of my 2024 best game on my list oh please think about this when the MC'S is the most powerful or at very powerful rank could you like give him some thing like an armor or something that shows yes he is the supreme one and like a good divine sword that is exotic like this or exactly like this it would be so good because how can you the most powerful being in existence and not have a supreme weapon like this be and it would be the most powerful weapon in existence like the Mc please think about and the armor could or might be like this
