Meh I thought farlander was just thrown out there. Endermen least give props to the slenderman which the mob is based on.
Besides can't have farlander and creeper. Too many 'er' ending mobs.
Guess you're right. The "farlander" thing came from, if memory serves, Notch failing to make some lore behind endermen, and stating that they came from the far lands (which, if you're not familiar with them, are the mythical lands approximately two and a half to five times Earth's diameter away from the center of the map.
Or, uh, thirty something million blocks away from the center. I really don't remember.
So, at that point the game just fails to generate any more chunks. The light fails to work and the areas are pitch-black, and the dropped items have serious troble to update in regards to players' position, whatever that means.
Oh, and the far lands got supposedly fixed. That means more or less that the terrain generation of the chunks past the boundary is pretty much fine as always. However other funny phenomena still ocur.
Just
go there and see the screenshots to get an idea of what I'm talking about.
Yeah, it's supposedly the past. The freaky landscapes are gone.
