Need help with an "All Dwarf" Campaign Idea. (GM coming out of retirement)

[PangolinPie]

Yeah so the Hobbit movie really rekindled an old fondness I've had for dwarves since I first read the book back in middle school so now I'm considering running my first game in nearly a decade, but wanted to get peoples opinions on what supplements or content I should look into that would be useful here.

I was thinking of just doing a full Underdark campaign; would be easy to integrate the all dwarf themed rather easily. A group of dwarves accidentally plummet deep into the Underdark, becoming lost and now have to find their way home, running into all manner of encounters and adventures along the way. I'm going for a simple concept given the fact that its been quite a while since I've done this.

So any suggestions/opinions on this?

Reminds me of this (http://agc.deskslave.org/comic_viewer.html?goNumber=247).

Thirteen dwarf fighters, one halfling rogue, and one human wizard isn't exactly the ideal adventuring party. A party of all dwarves with a good mix of classes would be good, and in the underdark just be sure everyone has a Ring of the Darkhidden.

Bend the forks, smash the plates, that's what Bilbo Baggins hates!

i'd be a Dwarf Rogue/warlock eldritch glaive sneak attacker.

If you want a minimum of books on the subject, I'd say...
Drow of the Underdark
Forgotten Realms - Underdark
Lords of Madness
Races of Stone
Have useful information on the setting. Add in the completes and MMs and such, and it should be fine.
If you want Mind Flayers as the Big Bads, I'd reccomend augmenting psionics with The DSP Wiki (http://dsp-d20-srd.wikidot.com/) and Hyperconscious (but that's a good idea for all psionics).
Alternatively, might I recommend E6? It's far better for portraying the low level sort of campaign you seem to be going for.
