This site, Gizmodo, has some very cool examples of steampunk constructions. And this site shows How to Draw Steampunk Machines.
Today in my mind I'm formulating a gnome bard character, using a lot of the feats and an alternate class feature from Complete Mage. If/when I actually stat him/her out, I'll post it here.
But I need to be spending time on the upcoming campaign that bridges The Shattered Gates of Slaughtergarde and Expedition to the Demonweb Pits. I have enough to keep them active for a little bit, but need to get further ahead.
