Longnight

On the longest night of the year, every fire in Marrowdown is put out and the whole town goes underground.

Nine hundred people. One fire. Sixteen hours. In cellars that have always been colder than they should be.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔥 FOUR HOURS IN

Something comes up out of the dark end of the room, towards the fire.

It is not hunting anybody.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚖️ THE THING THAT MAKES IT HARD

Keep them off the fire and they simply wait at the edge of the light. All night. And do not attack.

Which means the party spends Longnight guarding a fire from something that has done nothing wrong yet.

🎲 A 44-page one-shot adventure for D&D 5e — 3-4 hours, 4 players, level 3.

📦 WHAT YOU GET — 43 pages, nothing left for you to invent

▪ 5 scenes, every one written out in full: read-aloud text, what happens if they fail, what to do if they skip it

▪ 2 battle maps in three versions each — DM, player, and a copy with no grid. 70 px per 5-foot square, so it drops straight into Roll20 or Foundry already aligned

▪ 4 ready-to-play 3rd-level characters, finished — ability scores, armour class, hit points, attacks, spells and gear. Hand them out and roll

▪ Every character in it, player and NPC alike, has a drawn portrait

▪ A plain-English glossary of the basic rules words — DC, saving throws, advantage

▪ A section for your first time running a game

▪ A summary up front listing every scene with its page and how hard each fight is

▪ 10 secrets, tables and handouts, and written help for when the party goes sideways

🗓️ PART OF THE LOWMERE YEAR

Sixteen adventures in one valley, spring to winter, collected in one campaign book with a finale that is not sold on its own.

This adventure stands completely alone — it needs nothing from any other — but a table that plays four of them starts seeing the year take shape.

Mayor Bertrand Pell is in this one, and in two more of them.

✨ THIS IS FOR YOU IF

▪ You want a dnd horror one shot where the monster has a reason and it is not malice

▪ Your table likes a siege in the dark with one light source

▪ You want the decision to be whether to fight at all

▪ You are new to running games and want the read-aloud text already written

▪ You run on Roll20 or Foundry and want maps that import at the right scale

▪ You want to hand out finished characters instead of spending session one building them

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📄 THE FILES

Four PDFs, plus the maps.

▪ A4 — 44 pages, colour and printer-friendly

▪ US Letter — 47 pages, colour and printer-friendly

▪ 6 map images

🗺️ The battle maps also print at table scale — two extra PDFs, A4 and US Letter, lay every map out at one inch per five-foot square across numbered sheets with a cut line. Print them at home, tape them together and put miniatures on them.

The printer-friendly build is the same book in pure white, nothing removed.

⬇️ Instant digital download. Nothing is posted to you.

Games for a table, and for a chair by the fire.
