Areas in the game that we can see, but can't explore.

There's the lighthouse in Western Thanalan, and it's always bugged me a bit that you can get right up to the door, but not climb it. I want to see the view from up there!

In beta 3, it seems we could go to Mor Dhona from South Shroud : http://i.imgur.com/pEQUAAN.jpg

I would like to visit the tower outside of La Nocsea (sp) that the Yellow Jackets are guarding. It doesn't seem to be connected to the city itself and I want to know what is in there! Maybe it is the Illuminati's hideout?

[Seoulstar]

Is it weird that I want to see where those tracks lead to in thanalan after they go in the tunnel?

[Ecks007]

For Nym I want to see them use jumping sorta like t3 but maybe make them more a puzzle than a straight run.

I dunno about jumping, some of those floating islands are just too far apart. I was thinking something more like Cape Riverne in XI, they had these tears, or maybe they'll use portals.

There is a garlean aether-gate and base in western coerthas that we do not have access to yet

[Deedsie]

Castrum Oriens is still sitting there in the Black Shroud without having anything done with it.

And that point is now the entrance to Lost City of Amdapor. That point would have been geographically possible, but guess the idea was scrapped and the location used for Amdapor instead. It was never more than an idea (except maybe some old devbuild), Mor Dhona and Coerthas were never accessible before open beta.

[Alukah]

Yeah that one.

That's something new cos I totally ignored beast tribe stuffs

What's inside?

It's pretty empty, a few bomb-making machines can appear depending on what quest you have.

Also looking west from Camp Tranquill, to the side of where The Lost City of Amdapor's supposed entrance is, there's a huge reach of cliffs and mountains that have large jagged edges sticking out of it. A perfect badlands enviroment to explore with no way to get there.

If you look carefully at the road you take from north shroud to central coerthas behind the dot line, you can see that the path goes a bit north from that badlands, and since the griffin cross got trashed badly to the point they closed it for reparation, I thing it's safe to assume that it's what is left of the eastern lowlands

Also the map concept art says that the big ass door in north shroud is the "ruin dungeon entrance"
