Where is the Underworld?

Underworld... the almighty place where everyone is farming...
I came as far as Ring of Fire, only 2 missions left after that one, and I still haven't found the Underworld.
I used search, got a bunch of Underworld builds, not even this site tells where the Underworld is http://guildwars.gamepressure.com/index.asp
I even used flash map on Guru site but it showed nothing of it.

So where is it

Ah, but you have to learn how to use Search effectively.

Search: Key Word(s): Underworld, location

Anything you could possibly need to know aside from a few builds you could also search for. Closed.
