Evil druid (3.5)

[Maho-Tsukai]

Are you allowed homebrew? If so then Frank and K made a PrC in the Tome of Necromancy for druids that makes them able to be effective necromancers. You gain powers that can animate undead and do other fun things including wildshape into a whisp. I forget the name of the class but like everything frank and K make it's pure awesomeness and unlike the blighter is pro-nature yet still distinctly evil. I believe the class was called the "Corpselight Whisperer" but I am not fully sure. Still, if you are allowed homebrew you may want to check it out.
