Harnworld is a role-playing game campaign set on the fictional planet Kethira, and focussed mainly on Hârn, an island about three times the size of Great Britain, as well as Lythia, the world's largest continent.
Broadly based on Norman England, it is a low-fantasy setting with minimal magic and no mythical "monsters"; some sense of fantasy is provided by the inclusion of dwarves, elves and orcs.
[3] HârnWorld was written by N. Robin Crossby, Tom Dalgliesh, and Edwin King, with additional contributions by Brad Carter, Brian Clemens, Rob Duff, Mike Dwyer, John Frazer, Doug Gillanders, John Greer, Stephen Hinchcliffe, David Kowan, Sharon MacLeod, Simon Matthews, Brad Murray, Gene Siegel, and Garry Steinhilber.
[3] Lisa Stevens reviewed HârnWorld in White Wolf #22 (Aug./Sept., 1990), rating it a 4 out of 5 and stated that "Overall, Hârn is the best campaign world I have come across in my years of gaming and my recommendation is unreserved.
He noted that "Harn World emphasizes culture and economics at the expense of magic and monsters, making it less appealing to hack'n'slashers than to veterans who take their games seriously."
