How deep does the Underdark go?

I'm toying with creating a new fantasy world, and one question that came up
is--how deep does deep go, in the Underdark?  I don't have any standard of
comparison--how deep do modern mines go?  How far have modules delved?  Any
opinions?

I toyed with the underdark for a while in my fantasy world, and probably
will toy with it again.  Even though I've more or less estabilshed that
the planet on which my world sits is round, I figure that it is a
fantasy world so all sorts of improbable things can happen.

That being said, I don't think that the characters ever made it even
1000 feet underground.  They talked to some residents of the underdark,
who referred to interconnecting caves and passages that form a
three-dimensional underground world that spans much of the known surface
world-- "a whole new world" in other words.  The characters in this
world had been into "dungeons" before, but never into the interconnected
underdark.

I haven't yet decided how much I will do with this, although I have set
up a "loosely allied" state (a very small one) underneath the wilderness
kingdom that the PCs in this world are currently trying to found.

IIRC, the deepest mine in the real world is delves down 2 miles (it is a
diamond mine in South Africa).

As deep as you need it to.

>I don't have any standard of comparison--how deep do modern mines go?

I don't  remember, but I think it is in miles.

>How far have modules delved?

The concept is meaningless.   This will be your world and you don't have to
go deeper than anyone else or even stray far from the surface.

>Any opinions?


Unless you are going to worry about your world being a sphere or a plane,
the underlying geophysics can be whatever you want.   Personally I like my
fantasy worlds to be obviously different from reality in as many ways as
possible.   Therefore I would prefer the "Underdark" to be different.

Either there is never a problem with breathing or there is some wierd
eco-system which absorbs methane and carbon dioxide and releases oxygen.
It won't be photosynthesis!

As the GM you need to know the geological history of your world.   How did
it come to be the way it is?   Are there fossils?   Is there any coal?   If
so was it made from squashed trees?
How do gems come into the world?

You can have any answers you like, and you don't have to tell your players
in advance.
But if you don't know, then your dwarfs are going to be a problem becasue
they are supposed to know these things even if the players haven't the
slightest idea.   When it suddenly matters how hard or soft the rock is, or
what would  live on, or what the  are doing
here - you need to talk fast and convincingly.

I can spin details into a land on the fly, but I have to know my frame of
reference first.

Rgds,
Michael.

well, i don't really know off hand, but i can tell you that it's not 
as far as you'd think.  the deepest level of Carlsbad caverns is 
about 1300' below the ground.  i can't remember for certain, but the 
entrances to Wind and Jewel caves are only on the order of a hundred 
or two feet down (though they extend a few hundred or so feet below 
that point).  poking Google comes up with at least one cave that 
reaches 1600+m of depth, though it looks like the bulk of the cave is 
rather less deep (the maps are not of a style i know how to read). 
go here: .

europe's deepest mine (at least according to one source) is about 
1400m deep.  the world's deepest horizontal oil well is ~6500m.

  Earth's crust ranges from 5 to 25 miles in thickness.  i seem to 
remember that the mantle would make caverns uninhabitable within 
several miles of it.  but that still leaves you on the order of a 
dozen or a score of miles of depth for caverns.  though, of course, 
the deeper you go the more likely you'll run into lava, especially in 
a volcanically active area.

  anyway, this isexactly the sort of info that the web is great for finding.
