First held in 1998 in West Lebanon, Carnage grew from the motivation "to give New England gamers a place where they could come, be themselves, enjoy their games and have fun." After its inaugural year in New Hampshire, Carnage based itself on the Vermont side of the Upper Valley, moving to Brownsville, VTin 1999 and then to Fairlee in 2003. In 2012, the organizers announced Carnage 2013 would be held at the Killington Grand Hotel.
