This Systems Reference Document (SRD) is aimed at artists, designers, writers, and publishers who’d like to build on and/or adapt the rules and ideas found in Beak, Feather, & Bone, a tabletop roleplaying game by Tyler Crumrine. The BFB SRD includes the core mechanics for playing a game of Beak, Feather, & Bone, which are available for use under the Creative Commons Attribution 4.0 (CC-BY) License. What is doesn’t include are any of the specific play examples, worldbuilding, or artwork from the full Beak, Feather, & Bone publication. You must create your own original material when using the Beak, Feather, & Bone system as a base. Once you’ve created your own game, supplement, sub-system, or minigame based on the material within the BFB SRD, though, you are free to create, distribute, and sell that derivative work to your heart’s content. SO YOU COULD MAKE a genre re-skin of Beak, Feather, & Bone additional communities for use in BFB games map-packs intended for use with BFB additional rules to expand on existing BFB play a session zero minigame in your own RPG and much more! All that we require is that you make a clear statement that your game is based on BFB’s material. This document contains the text required for that statement, a break-down of BFB's core mechanics, and tips on naming, art direction, and style. Source: The Developer Website.
