The Rational Magic Kickstarter is now live. Rational Magic is a campaign filled with investigation, intrigue, and espionage set in a gritty dystopian fantasy world; a world that evolved from a traditional sword and sorcery setting. Players are Operatives who work either to maintain the status quo or rebel against the forces of magical modernity. Rational Magic is for 5th edition, as well as the Lore System RPG, which was purpose-built for this campaign.

Rational Magic uses two system "hacks" to support investigation and espionage: a Risk Counter and Lore Sheets. Lore Sheets are handouts that provide players with extra background information about their characters and the game world, and Lore Sheets can be used to assign special roles to each player character. Risk Counters are a count-down mechanism which conveys to the players the amount of risk that is in a scene. They are used for scenes which include elements of stealth and investigation.
