Main dialogue
In order to become stronger, you must experience more worldly things, which means you should expand your horizon by leaving this island. Staying here in 140000000 will only get you so far.
Press W to open the world map. You'll see the whole world that you have forgotten, the world which you had fought so hard to save. Of all the places listed here, you should…
...head over to Victoria Island first. There you'll be able to meet new people, battle different types of monsters, and gain invaluable experiences. Since you have lost all of your memory, your mind should be a blank canvas right now. Use this experience to soak up as much as you can, so that the next time you face the Black Mage, you will be able to look at him in the eye and not even flinch.

There's actually a person there in Victoria Island that should be able to help you on your journey. Mr. Truth, or 1002104, as he's called by the outside world, should be there. He's an Information Dealer in 104000000. Take this letter, and he'll recognize you at once.
Finding 104000000 in Victoria Island is easy. Exit the town to the right, then walk past the snowy forest and you'll see a small harbor which the penguins operate. There, strike a conversation with 1200003 and get on board.
Main dialogue

…I can't believe it. I'm standing in front of a hero. I used to live on that island myself, and I also used to believe the prophecy, but… oh my goodness. 1201000's wishes have finally come true. What? You want to know what I was just talking about?
After discovering the Book of Prophecy, our race has been bracing for your inevitable resurrection for hundreds of years… all in that tiny island with nothing but ice… but the hero never came, and we've been slowly losing our faith in the prophecy.
In the end, most people left 140000000, tired of waiting for the prophecy that never came true. I just hope you don't blame them for leaving. They had to do what they had to do, you know. But, that being said…
1201000 was the one person that never lost hope, and stayed in 140000000 long after everyone else left, holding onto the belief that the hero will someday come back and save us. Even after her older brother left the island. That's one stubborn kid, I tell you.
But now that you're here, that stubborness has been rewarded. Thank you for coming back. Now I can look 1201000 in the eye again. I have felt so bad for not being of any support to her, even though we are cousins.
Just tell me what you want to do, and I'll be there to help. Not just because you're the hero in our eyes, but also because you've validated 1201000.
