Lore

When Annam's children first began to populate the worlds of the Material Plane, the All-Father created behemoth dinosaurs to live alongside them as companions. The primeval magic used to create the dinosaurs still thrums through their being and manifests in colorful, scar-like lines on their towering bodies. Some of these ancient dinosaurs persist in timeless jungles, hidden enclaves, and other lands untouched by the rest of the world.
