Acho, The Older Brother

Elum explained, as they continued on, that the stone circle was built at the dawn of time, by a people before the Forest People, when the Great Forest was still young, before Abdazon, Ederron, or Old Qisuth. It was a great open air temple to Acho, the Older Brother, firstborn, whose enormous boulder stood at the center of the ring. When Anthuor first stepped out of the Hypogeum, his hoof struck the back of Acho, who supported him and who still bears the hoof marks high up at the place where Anthuor first came to Quatria, and nibbled the lichen growing there.
