module s4

Bilbo … saw that across the valley the stone-giants were out, and were hurling rocks at one another for a game, and catching them, and tossing them down into the darkness where they smashed among the trees far below, or splintered into little bits with a bang …

–JRR Tolkien, The Hobbit

This pair of stone giants has made a playground of an area where a minor rockslide once obstructed the pathway.  They have cleared the area to make a broad ground to run around on, and there they play catch with boulders.

–Gary Gygax, AD&D module S4: The Lost Caverns of Tsojcanth, TSR, 1982
