I have BW and was hoping to run it this year with my players, and was looking for a setting.
I just got the new book Adventure Burner, are you familiar with it?
If so would it be easy to use those adventures in Harn?
Yes, I have the Adventure Burner and think it's awesome. Not necessarily so much for the adventures themselves (although they've definitely been improved from the prior versions), but for stuff like the chapters on beliefs, and complications, etc. Really good advice on how to build both characters and stories and beliefs for a specific type of setting/campaign.
That said, I do think some of those adventures could be readily adapted for the Harnic setting. In fact, I ran a Harnic variant of "The Sword" (called "The Spear") a Harncon a few years ago. I don't think it actually went over very well because I upped the number of PCs to six, and tried to introduce some magic rules-- and I also had no prior experience running con games. But... I think the idea is basically sound and have the ideas for a revised version (strictly for four players) sketched out, with the characters having just discovered the spear of the great Jarin hero Barryn Albarra-- and the trying to resolve who gets it. Instead of a Dwarf, Elf, Man, and Ratman, however, the four characters are an Ivinian, a Jarin nationalist, priest of Ilvir, and an Ymodi barbarian instead. I think it would also be possible to run this as a an actual Harnic "sword" adventure, maybe with the Sword of Kalsten being the object instead. Really, it could be done with *any* artifact, that you could have four people all making a claim too.
I also think it could be really fun to do "The Gift" in the Harnic context, especially given the nearly thousand year lack of communication between the Sindarin and Khuzdul, and the truly profound hostility that the Khuzdul have. It may require tinkering with a few apects of the Harnic setting-- but that could maybe be done by setting it a few years in the future (724 TR, or so), when, following the surprise death of King Hamazdul of Azadmere, a delegation of Sindarin travels to Azadmere for his son's coronation/accession, in the hopes of repairing ties by offering him a truly rare and remarkable gift.
