From the introduction:
This adventure was designed for four characters in their first careers. These characters should have at least half their advances taken. With a little adjustment to names, places and stats, Selaa-Dunesh and be incorporated to any place in the Old World.
The course of events in this story will take a night or two to play out. Our heroes, such as they maybe, aid in the defense of a small Talabecland village. Where vicious and evil Beastmen plague and raid the small village, ravaging the populous. The villagers will plead for their help, and most noble-hearted characters should agree.
