You're the GM!

This scenario should do a pretty good job of helping you practice running a game. You'll want to start the game by asking your players to introduce themselves and their characters. The scenario should invent some players for you. e.g. "I see we have four players today! Why don't you introduce yourselves, starting with the person on my right?" You will be responsible for making any needed rolls and letting characters know how their actions work out. The scenario has no rules or dice built into it. You can help the AI out by making story cards for players and their characters.
