Scion

Another term for an "Aeon User", the Scion is one half of a Spiritualist Syzygy ; the "host" is known as the Scion, while the summoned entity is called the Aeon. In many contexts, the terms scion and spiritualist are used almost interchangeably, though they are not exactly the same thing; only a Spiritualist who has successfully formed a Bond with an Aeon may be called a Scion.
