DODMAN - Diviner of Odd Domains

'dodman' is an old English word for a land snail. According to some it is also an ancient word for a surveyor; one who divines and demarks ley lines.

This is a business card-sized tool for quickly and randomly generating pointcrawl maps using a coin, paper, pencil and a flat surface. By flipping or spinning the coin you'll determine the direction in which you draw your lines and points. It includes 42 different random features, ranging from familiar site to remains of a deity. It is largely era-agnostic.

You can use this:

a) as a standalone activity for creating a nice map you can embellish

b) as a starting point for creating a setting/map for your TTRPG campaign / one-shot

Note: included in the files is a black and white BLANK version which allows you to input your own features in the reverse side table (either digitally or by hand).

Designed for the Pleasure-not-Business Card RPG Jam.

Hi I managed to recreate the whole dodman algorithm in python. Do you mind if I posted it on github?


I would love it if you did! If you could just make sure to link back to here, that would be great.


Just uploaded it. The github link is as below:



This is really cool!


I need to remind myself how to make something like this work, but in the meantime I’ve put it out on Twitter for others to look at - hope that’s alright! https://twitter.com/valleyofalfred/status/1431309664181006342?s=21

(if you’re on Twitter, let me know and I’ll @mention you)

I don't mind having it shared. As of now I don't have a twitter though. Also I just updated the docs with some images.
