Like how he came to be able to afford being Lord a Master of Lost Forest…

…a burden he has apparently carried with him for years…

But did you ever see the gold?  And how did the stranger see anything?  Isn’t it dark in a cave??  Oh, that’s right, bioluminescence…

And what would you need of a map?  And isn’t it said that the cave opening moves around on its own?  Sort of like on Lost, when it became necessary for Benjamin Linus to move the island?
