Belciennes | Collaboration with The Griffon’s Saddlebag

Welcome all to Belciennes, the amphibious city of rangers and lilies! This release is unique in a couple of ways:

  • First and foremost this will be our first “one-shot” release, a self-contained city or district. While the city of Belciennes is larger than what we show here, we think this snapshot map should be all you need to run exciting Belciennes adventures.
  • This entire release is a collaboration with our friends over at The Griffon’s Saddlebag. Belciennes is a city in their setting of Amphibios (known as “Laterreprosp” by the locals). We’ve included their setting primer for you to start digging in, and there’s even more content over at Griff’s Patreon

As always, please let us know what you think of this! Our focus will always be large, full cities that are our own unique creations, but if you want more of these one-shots or setting collaborations, we’re happy to sprinkle them in more often. And obviously: we love frogs. Griff suggested we help out with a frog city, and we just couldn’t say no. With that out of the way, here’s the release!

Borough Guide

The city of Belciennes is the second largest town in the lowlands. It is home to the ruuns: frog- and toadfolk who have become the masters of this fertile valley. Belciennes lies on the frontlines of a war with the vengeful murkfolk and their draconic overlord Acridaethruix. Our guide gives you everything you need to know about the city, its famous Alabaster Lilies, and the fabled Marshwarden Coliseum. Plus, we set the stage for a thrilling rescue mission deep into murkfolk territory.


The city of Belciennes exists half above water, and half below. The marshy town on the shore of Vasteloc is a haven for new parents who bring their eggs to the lily pads to hatch. Tiny canals line the city streets, perfect for tadpoles to accompany their parents on daily tasks. Of course, we also provide a view that shows the underwater frog homes. Make no mistake: this city was not built with humans first in mind. We’ve also got two additional variants for this mapE28094misty and rainyE28094to really hammer home the dampness of this setting.

Patrons at the Chief Courier tier or higher also gain access to the interior of the Marshwarden Coliseum. This large training ground is where fledgling rangers hone their skills and prepare for the war against The Murk. As such, the lower floors are dedicated to blowgun marksmanship, underwater assaults, and all of the amphibious shenanigans expected of the elite ruuns.


Come on. If you see a coliseum in a map, you know we’re going to give you some combat music. “Allies Against the Murk” is your perfectly proud marshwarden fanfare. Big brass and bright and colorful woodwinds are the perfect underscore for challenges in the arena or daring missions into enemy territory. Plus, if you just want some basic underscoring for intense moments, we’ve got a stripped down version that just features the bold underlying percussion.

Amphibios/Laterreprosp | Collaboration with The Griffon’s Saddlebag

This entire setting was dreamed up by The Griffon’s Saddlebag, hinted at in tantalizing flavor text from a handful of his previous items. The legendary hero Sir Alec Varion has been in the background of the Saddleverse for quite some time, and now we finally know the whole story of the great knight, his marshy home, and the world he inhabited. The 15-page document that accompanies our own borough guide will show you the capital of Oudaarde, the threatening lair of Acridaethruix, countless adventure hooks, and a slew of new 5e statblocks to help you bring Amphibios adventures to life.
