Jean Wells, one of the early pioneers of gaming and long time TSR developer has passed.
Here are some of the links that can better explain her contributions than I can.
Among her other contributions to the game and to the hobby she was also famous, or even infamous, for her original B3 Palace of the Silver Princess module.
B3 was one of the first adventures I bought to run as a DM and read and reread that adventure 100s of times.
A sad day in gaming indeed.
