This is not how you tell a story.
Imagine you are a story teller in some medieval market. You stand up in the fire light to tell your story and hope they’ll throw you enough coins to keep going, enough coins to live another month, another year.
If you start with “Fifty years ago the magical empire of—“ they’re going to throw chicken bones at your head. What’s more, you’ll deserve it. And if you start with a list of characters and their ranks and professions, by rights they should run you out of town at sword point, though I hear some communities are more lenient.
But you are, first and foremost a story teller. You have a minute, there, in the light of the fire, to cast your spell and have these people give you money they could spend on chicken or beer.
Tell them the story. Start mid-action. Explain nothing. Make sure everything is implied in the tone and opening, then pile on it by little actions, little gestures, little flashbacks. Keep the spell going. Keep the story spinning. Your turn.
*For bonus points, tell me what information you can glean from each of the snippets! (beyond “Sarah is a meany mean person of meanness who teases us” natch.)
