From publisher blurb:
This is our 36th installment of the one-page dungeon series. The objective is to create self-contained adventures/dungeons with all things necessary to spawn fun adventures on a single page. It is system-neutral so it can be easily ported to any system. It shouldn't be much trouble to include it in any medieval setting.
In Chapel of Lost Letters, the characters visit the tomb of a valiant knight who spent his life trying to defend the weak and to deliver messages of love to faraway individuals. Today, to honor that tradition, people bring letters addressed to the dead to the tomb. Unfortunately, the feelings of regret, anguish, and pain have bottled up and caused the dead knights to be possessed and become undead. Do the heroes have what it takes to cleanse this once-peaceful shrine?
Denizens of the Tower! Here's a fantastic one-page dungeon. It's a self-contained adventure where everything you need fits on a single page. They are system-neutral so they can be easily ported to any system. While no system rulings are included, we made this one thinking of Shadowdark RPG. Still, it is neutral and can be ported to any medieval fantasy system/setting.
