In 1984, TSR published the module B7: Rahasia. It was written by Tracy and Laura Hickman and illustrated by Jeff Easley and Timothy Truman, and consisted of a 32 page booklet and cover folder containing maps. "Rahasia" was originally published in 1979 by Hickman under his publishing imprint Daystar West Media, and again in 1983 by TSR as "RPGA1 Rahasia", available only to RPGA members.
This conversion guide allows DMs to run the original module with 5th Edition rules and provides a reference sheet for encounters. It is intended for 5-6 characters of levels 1-2 or 4 characters of level 3.
To use this conversion guide you will need a copy of "B7 Rahasia".
