Castaway's Journal - Day 6

There's something odd that's bothered me since I arrived here. Far off in the distance, I can see what looks like an enormous tree—big enough to be the so-called |world tree| spoken about in so many myths.
Still, it's so large that no amount of fog would be enough to obscure it from view from outside the island.
The only hypothesis I can come up with is that something other than the fog enveloping this island prevents it from being seen by the outside world.
In other words, some kind of mechanism must be preventing it from being seen from the outside.
It seems likely that the mysterious powers these Pals have have something to do with them.
