From the publisher's website:
Upon Foundations of Stone
Beneath the walls and towers of adventure, beneath the ground upon which the adventurer treads, lies the foundation. It is that which holds the construct, which drives the challenges, which brings the flavor of a world’s imaginings to light. It is the maelstrom of creation through whose eye the game of heroic chance plays out.
What Lies Within

From world creation, to dungeon designs, managing non-player characters, character attributes at high levels, spell use and cost, equipment its use and wastage, the tumult of storms, from warfare to combat, monsters, treasure, death and more.
