top one I can confirm is useless, i got up there. theres no set warp so its useless, and so is the pyramid, ive been there. useless. the middle one is probably the same. also, the sign wont have any text on it, and if you try to get up there, you'll get warped. Honestly dude, you should just download the old maps and look around on them.

Seriously though, all of these are from the old map. Destiny was from the old map, and they brang it back. You know that door in southwest swamp? That used to lead to Babord I think.
