Elijah goes to Ganed and his echo shows him all that he has learned. At the site of an ancient tree, there was once a primitive Ganedan that was killed by an aquatic Aleph. This specific Ganedan was the son of King Faerela, who commanded the Ganedans to re-enact the murder, which became a traditional ritual. It's no wonder that there is such strife between the two communities.
