"The Midderlands is an old-school game setting with bestiary for use with old-school role-playing games. It is based on Swords & Wizardry Complete, but could easily be used with other old-school systems and even non-OSR systems such as D&D or Pathfinder.
It is a green-hued, dark-fantasy, late-middle ages, early-renaissance view through grime-smeared spectacles. The setting itself is based on an area in the middle of England near where I live called The Midlands. Many of the locations are loosely based on reality, but others are pure fantasy from an addled mind.
The setting part of the book contains something I call "game-juice". Not heavy of history and monotonous detail, but enough to get the game-juices flowing and let the game master twist and tweak as they need to in order to fit their campaign."
