Cool paint job!
The warlock figure was based on a John Blanche cover for warlord magazine, and was a redesign of a picture drawn by a reader for a competition. He is not, as often said, the warlock of firetop mountain!
The chaosette was sold as a two pack originally as a limited edition, though it was never announced how many where made.
The warlock goes for a higher price on eBay- Though he isn't really rare as such- you see one every month or so. watch for broken index finger.
The chaosette appears much more frequently, you can usually grab one for around five pounds sterling - I suspect she was rereleased and rolled into the chaos warriors at some stage, but that's speculation on my part- you see her a lot more often.
I am sculpting a proper shield for the amazon based directly on johns artwork- shame I can't sell it!
