Legacy of Blackscale Lagoon is an introductory-level adventure (levels 1-3) for Swords & Wizardry, written by award-winning author James Spahn.
The adventure takes place in the swamps of Blackscale Valley, and is structured with a home base, sandbox wilderness region, one major adventuring location and several smaller lairs to discover while exploring.
What starts out as an ordinary venture into the backwater (and very watery) swamps of Blackscale Valley turns into a complex mystery about the events that took place in the Valley about a hundred years ago. Not everything is what it appears to be, and peril awaits the characters at every turn!
