Answer:
I have been in productions before, and written plays myself, so I hope this helps.
Step-by-step explanation:
Open with still actors, the narrator comes on the stage, and explains the setting, like, when and where the story is taking place. Narrator goes to the side of the stage, and the scene begins. Since I do not know the type of play you're doing, I don't know how you wanna take the first scene. Maybe open on a busy village? I really hope this helps!
