Just wondering. Are the names and "aspects" of the demon lords and whatnot Open Content? Can I publish my own .pdf using Mephistophales, or Graz'zt, as established by Wizards? (By as established, I mean more fluff-wise, as I would like to rewrite thier stats.) If not, how much about them can I use?
Thanks,
