In reference to Atlantica, Triton spoke about keyblade bearers being bringers of darkness and destruction. So clearly a different keyblader has visited that world. So the question is now, which one has? One we don't know?

My bet is Master Xehanort.

He said " The Keyblade bearer shatters peace, and brings ruin." He just means that wherever the Keyblade bearer goes, destruction (in this case the Heartless) follows. I doubt he was talking about one specific person. It's all the legend of the Keyblade.

Im sure Triton...being a King in his own world is knowledgeable about the worlds and its workings just like King Micky. I honestly dont think there is a deeper meaning here but i guess you never know.

Reading too much into this, eh?

I don't think Triton meet a wielder before Sora. He just knew of their existence and the Legends around them. Those Legends might have been handed down from the Keyblade War.

Well, I don't think we should just presume the rulers of worlds know about Keyblade Wielders. I'm sure there are lots of worlds where the rulers had no clue about them. To me, this is just one of those things that someone has overlooked and when it's asked you probably get told 'a wizard did it.'

THIS AGAIN?

Anyway, I doubt anyone has gone to Atlantica before. He probably just had knowlage

For people who said it's a legend and know body came to Atlanitica : if no keyblader visited Atlantia how did they knew about that legend !? , just think about it !

True. I was think about it in terms of recent history, if Triton himself met a Wielder. You are correct, a keyblade wielder would have visited Atlantica at some point.
