Arcadia Quest: Pets is not only a campaign expansion, bringing a whole new campaign, with new scenarios, monsters, heroes, rewards, and titles, for use with either the original Arcadia Quest or the Arcadia Quest: Inferno core boxes, but it's also a modular expansion that introduces Pets, a brand new system that can be added to ANY Arcadia Quest experience. This includes classic Arcadia Quest, Arcadia Quest: Inferno, Beyond the Grave and even Frost Dragon, The Fall of Arcadia and anything else Cool Mini or Not come up with.
