L1. The Secret of Bone Hill
This 1981 adventure is the direct prequel to L2, which we ran earlier. It takes place on an island, and L3, written in 1979 was published late in the 90s as part of a special anniversary collection for D&D. A fourth one was also released by the author, to add another entry to this series, set on an island in the land of Oerth. (Greyhawk).
It’s a nice module, and looks the part of an early module, with a lot of setting (such as maps of towns and shops and such) and details, (and virtually every NPC has a class and level) but a weaker plot that allows the GM to flesh it out. It resembles modules such as T1 The Village of Hommlet and N1 Against the Cult of the Reptile God. This one will require a bit more work to make it work with the location of Arjuna and Hamedh, but it’s quite doable.
