The Character Cache is a collection of characters designed to be used in tabletop RPG gaming, either as character concepts for players or as NPCs/villains by GMs. Artist Matt Morrow illustrates the character pieces, and Encoded Designs writes a system-neutral description, including how to incorporate this character into your campaign. These write-ups also include hooks for encounters and adventure inspiration, plus tags for quick reference.
In addition to the system-neutral write-up are stat blocks for:
Fate Core
Savage Worlds
