Alright, well! The Holyland isn't somewhere you can get to by ordinary means… how it came to be doesn't appear in stories much, but I assume that when the Goddess turned herself into the Mana Tree, she split off the land the Tree grew in as well, so that no one would be able to disturb her without going through a lot of trouble first. It's not quite attached to the rest of the world, you see- we had to open a gate to get there.
