I have added two I found on this site:
home.gwi.net/~rdorman/frilond/rul/dm/index.html
It has this blurb which I found interesting...are there more?
The cavewight debuted in "Chronicle Monsters" by Lewis Pulsipher, from White Dwarf 16 (Dec 1979/Jan 1980). This article converted several monsters from Stephen Donaldson's fantasy trilogy the Chronicles of Thomas Covenant, Unbeliever into AD&D terms. Pulsipher was a frequent contribute to both the Dragon and White Dwarf; his most famed D&D contribution is probably the Elemental Princes of Evil. His Donaldson conversion proved so popular that it was reprinted in the first Best of the White Dwarf collection.
Does anybody have White Dwarf magazines?
