Stonehead was a big part of the Rock Lords theme. This fortress featured heavily in the movie, packaging artwork and minicomic that came with the toys. It never received any sort of toy however. In the eighties, it seemed that every toyline got a big playset, and at the design stage, Rock Lords was no exception. It seems that the heavy focus on Stonehead was indeed meant to increase interest in the Stonehead playset; only it was never released.
