G - Giants

The Classic TSR Adventure Series!

There was a non-official module published by another company that was intended to expand the series: GS1: Sanctum of the Stone Giant Lord. This module was originally published with the series code G4 to show this link, but the code was changed to GS1 within the year that it was originally published.

N.B.
As the original G1, G2, G3 modules passed into "classic" status, a variety of 3rd party or fan-made products sought to extend the series or interact with the narrative arc in a variety of methods. Many of the items linked to this series were never published by TSR, etc.
