The Campaign World
The original inspiration for this campaign comes for the Solomon Kane stories Written by Robert E. Howard and The Baroque Cycle written by Neil Stephenson. This campaign is set in the historical world of the 17th century. This would seem to be a bit later than the Solomon Kane stories, although Howard never really specified a date in any of his tales. The transformations begun in the 1500’s, the Renniasance, the Reformation, and the Age of Discovery have culminated in a truly new world. Here are some links to wiki pages that gives a lot of great background to this time period.
While this is an historically set game, the characters will be up against all manner of supernatural opponents as was Solomon Kane and magic does exist albiet in a much more subdued manner than most fantasy settings.
