The Mechanical Woodsman and Other Stories

From the intro: The Mechanical Woodsman and Other Stories is a collection of scenarios for any d20 fantasy campaign, and for a variety of power levels. Each story can be told in one session, and each features elements of clockwork-based magic. Most players are unfamiliar with such magic, being more used to orcs and dragons and other threats of the flesh. Consider these stories an interesting detour into wind-up fantasy.
