Spiral

Premise
The system is open: it’s just a frame of rules that will let you play in different environments. But you can’t just create any kind of adventures: the games created by "Spiral" will be tied to a very specific theme. This theme can be addressed by a couple of questions: "what can you lose to gain power?" and "what makes you human?" Combine the two questions and you’ll have the game. But you'll see better later.
