Free GM Resource: Mithril Mages Random Tables
Mithril and Mages is a website with a ton of random generators. If you go to the homepage you'll find a fancy interface/page and many of the generators themselves are also "fancy" pages.
Me...I prefer to go straight to the utilities page, which is quicker loading and lists all the table. I'm also a bigger fan of the Labyrinth Lord tables than the others, but there is a lot of usefulness here....
