The echo is a near 1:1 reflection of the Karnosea in its natural state, meaning there are no man-made structures in the echo. Anima live in the Echo and are created by Ilena, the Goddess of Creation, when a human is born in Karnosea. Anima are the Id, the instinctual soul of a human and take on the animal form of a human. If an Anima dies by any means in this world, its human counterpart will also die and vice-versa. Being animal Id and behaving like animals in the Echo, some anima may hunt or be hunted by other Anima such as the in Karnosea and circle of life.
