From publisher blurb: This rules supplement allows you to play 7th Sea (1st or 2nd Edition) without a Games Master. Questions about your the world and the actions of all the NPCs that you would normally ask your GM are handled by a few simple tables and one or two dice rolls. Rules are provided for simple and complex questions, scene objectives, NPC actions and combat tactics. Alongside the printed rules is a single plage HTML document that condense all the tables and dice rolls into a simple javascript. This can then be run on any smart phone, tablet, PC or Mac. The HTML version also provides a handly dice roller for up to 10 dice and handles exploding dice and totals the kept dice.
