Why is it that some of the largest animals live in the Volcano? The Ash Loa-Shan occasionally, Gravios, Akantor, Crimson Fatalis, etc. There just does not seem to be enough food to support creatures of that scale. And I seriously doubt that a full-grown Gravios could be supported on Iron and coal alone. Sure the Akantor could prey on Gravios, and the Crimson Fatalis would be challenged only by the Akantor, but what about the Shogun? Or the Agnaktor? The Ash Loa-Shan could swallow heards of passing Aptonoth, but he doesn't need to eat often anyway. But it all depends on the Gravios and Shogun, how would they live, the entire ecosystem depends on them.
