The Waterline D&D 5e One Shot Adventure – Level 5, 4 Players (PDF)

There is a line on the old stone in this valley, about nine feet up, on everything older than the town. Nobody in Lowmere mentions it, and every house any of them has ever lived in stands below it.

On Tuesday the Marrowdown well dropped forty feet in an hour and did not come back. Since Thursday the drying shed floor has been under an inch of water that is coming up, not in. Somebody has to go down the well and find out which of those two facts is the good news.

LIGHT IS THE ADVENTURE. Oil is the clock, tracked openly on the page, and it is what makes every decision at the bottom cost something - no spell trivialises the choice, only the descent.

WHAT YOU GET - 38 pages, and 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
- 3 battle maps in three versions each: DM, player, and no grid. 70 px per 5-foot square
- 4 ready-to-play 5th-level characters
- Full stat blocks printed beside the scene that uses them
- 11 secrets, tables and handouts, and written help for when the party goes sideways

A complete evening on its own, and the strangest one in the line - you go all the way down, and you do not find out who cut the drain. That is deliberate.
THE FILES - four PDFs: A4 and US Letter, each in colour and in a printer-friendly build. The printer-friendly version is the same book in pure white, nothing removed. Plus 9 map images.

Compatible with Fifth Edition. Instant digital download - nothing is posted.
