Clockwork

From the introduction:

Rava. Ariadne. The Gear Goddess. The Clockwork Oracle. Mother of Industry, Spinner of Fate, Merchant Goddess, Patron of the City of Zobeck, Patron of Weavers and the Gearforged... whatever mask she wears, hers is the Plane of Gears, an endlessly turning demesne of cogs and metal. Here, on a field of brass far from any civilization, lies the Burnished Grove. From a distance, the sprawling copse of trees seems an organic anomaly within this strange land of steam and machinery. But on closer inspection, the true nature of this forest is revealed: every tree, bush, leaf, and blossom are composed of hammered metal and inexorably turning clockwork.
