Prep a D&D Session in 30 Minutes: A One-Page Checklist

You have half an hour before everyone arrives. Your adventure PDF is open, your notes run across three documents, and you still cannot find the name of the person waiting at the bridge. This is a good moment to make one useful page.
The routine below works best with an adventure you have already read, or a small situation you understand. Thirty minutes will not teach you an unfamiliar campaign book. It can help you decide what you need in front of you tonight.
First five minutes: find the opening
Write one sentence describing what is happening when play begins. Add what makes it matter now and one decision the party can make.
For an original example, try this: the village ferry bell has vanished, fog is gathering, and the keeper needs it back before the evening crossing. The party can question the keeper, follow tracks along the bank, or ask the waiting passengers what they saw.
That gives you a place to start and several ways forward. You do not yet need a history of the village.
Next ten minutes: prepare three likely scenes
Give each scene a location, something the characters can discover, and a complication. Keep each entry short enough to find at a glance.
Ferry landing: fresh cart tracks leave the empty bell bracket; passengers argue about whether to wait.
Reed path: blue twine catches on a branch; rising water threatens the easiest route.
Marsh shrine: the bell hangs from a beam; the keeper's apprentice refuses to leave without his missing brother.
These are places the group might reach, not a compulsory sequence. A passenger could point directly toward the shrine. The party might hire a boat instead of following the path. Prepare what is there and let their choices connect the scenes.
Next ten minutes: people and clues
Give each important person a want and a worry. Mara, the ferry keeper, wants a safe crossing and fears losing the villagers' trust. Tavi, her apprentice, borrowed the bell to signal his brother in the fog. He wants help but worries that admitting the theft will cost him his place.

Now record the clues that make those facts discoverable. A passenger saw Tavi pushing a handcart. The twine matches cord used at the landing. A faint bell rings from the marsh whenever the wind drops. Each clue offers an actionable lead; finding every clue is unnecessary.
Leave the outcome open. The characters might recover the bell, search for the brother, organize another signal, or persuade the passengers to postpone the crossing. Your notes should help you respond to those choices.
Last five minutes: mark your references
Put page numbers or bookmarks beside rules and adventure details you expect to need. If a creature might appear, open its entry. Keep player-facing handouts separate from notes that reveal the answer.
Use five boxes on your page: Opening, Three scenes, People, Clues, References. Short phrases beat copied paragraphs here. Write down names you are likely to forget and leave a little space to record changes during play.
Know when you are ready
Before adding anything else, check five things: can you describe the opening, offer a meaningful choice, find an NPC's motive, provide a useful lead, and locate the rules you need? If so, put the pencil down.
You can invent the inn's wallpaper when someone asks. The useful preparation is already on the page, ready for the moment the players decide to do something you did not expect.
For your next session, choose a Penny Blood Adventures module you have read and try the five-box method on its opening situation.
