Elder Evils (2007) is a supplement for world or multiverse-ending Big Bads published by Wizards of the Coast. It contains nine primary antagonists (see below) with a host of subordinate or supporting lesser antagonists for each. I noticed that at least one of these (based on name, form, and defining traits), Zargon, originally appeared in the D&D module B4 The Lost City.
Elder Evils does a poor job citing the source material for its contents, and I want to know when and where these first appeared in TSR or Wizards of the Coast publications (notes about appearances in other media welcome, but not the direct answer I am looking for):
- Father Llymic
- The Hulks of Zoretha
- The Leviathan
- The Pandorym
- The Worm that Walks
- Zargon (1982, B4 The Lost City)
