has been doing adventure maps for years. And they are iconic. So iconic, it's very easy to rip him off and maybe not even know it. That's because he has perfected a craft of simplicity.
Dyson's Delves I is a 152 page book you can score in paperback or hardback from Lulu (link below). From the back of the book: "Being a collection of cartography and detailed adventures hand crafted by Dyson Logos, cartographer and explorer."
One-third of of the book is a series of detailed adventures, generally taking up 2 pages each with a map and keyed area descriptions. In the OSR spirit, these adventures are scripted, merely keyed. The stats are given in classic D&D terms (basic/expert). The adventures are for low level PCs ranging up to level 5-6.
All of these delves are part of the same quasi-megadungeon and you can string them together into an epic crawl or use them individually.
The rest of the book is a series of awesome maps with blank lines for you to fill with your own adventures. Just write in the book, dummy! It's POD.
Obviously the thing that makes this book great is Dyson's actual maps. They are just nice to look upon. They are works of art from a person who as mastered their craft. They demand to be explored. But in addition to that, the keyed adventures herein are pitch-perfect for a good old game of D&D where you roll 3d6 in order and die at zero hit points. You can pop this book out at the table without any preparations and run a game, no problem.
Dyson don't screw around. His maps are featured in the latest D&D 5e offering from Wizards of the Coast, Dragon Heist!
