From publisher blurb:
BR 1-3 The Adventures of Black Ridge Island is a Fantasy Adventure Module designed for AD&D 1st or 2nd edition. I recommend 6-8 characters of levels 1-3.
It is a compilation of three modules:
BR-1. Adventurers Wanted
BR-2. Xvarts: Silent but Deadly
BR-3. Revenge is Best Served Cold
Take your adventurers into a whirlwind adventure that sweeps them out of their safe environment and throws them onto an island, with minimal equipment where they have to use their skills and wits to survive the horrors of Black Ridge Island.
This 38 page module has everything you need to kick off a new campaign. And enough material for several weeks of playing.
Wanting to throw something different at your group, already run through all the mainstream modules, this is my own creation that I have run many times over my 30+ years of being a DM.
