Characters are moderated by a "Storyteller" that will act as your environment including your NPCs, weather, enemies and other things that might interact with you on your journey.
You role-play by doing actions. (Ex: *walks through forest*).
Sometimes you have to be specific when doing actions, so your actions can be effective.
During the course of your story, it will be monitored and documented on your character page and categorized based on Arcs. Arcs are the events that happen in the Sagas. Sagas are pre-released and set up by The Government itself. The story builds on itself as the arc does based on the events that occur during the journey of that arc building up a story.
