My latest 1-page adventure is now available for free! It is a hex-crawl for levels 4-7 using Labyrinth Lord rules. Here's a taste.
"Completing your last mission brought you to Lankwick, a town best forgotten. You await the infrequent arrival of a ship to return you to civilized lands. In the meantime, danger, disease and even treasure can be found in the evil reaches of Witches Fen."
This is most certainly a location based adventure. You will need to bring a little something to the party to use this, but I hope you find the map evocative for an afternoon's play.
