Since our group's been playing for so long, we've had time to come up with various table aids and alternative rule sets. Most of them are based on Dungeons and Dragons 3e, but they could easily be adapted to other games! Feel free to use these for your own (non-commercial) games and spread the fun!
If you've got a good aid or set of alternative rules you'd like to share, hit me up and I'll post them here!
