This Fairy's Streaming Light, put simply, is the power center of a Fae, or the energy source, a superior alternative to the Microtide Pearl and perfectly suitable as the prime material for the Fairy Bloodline.
The Fairy Potion formula provided by the Ellen Family had some minor differences from the one Ian got from Teacher Hiliad—the latter required a 'nourishing extract from a Spirit Energy Plant', whereas the Ellen Family's version modified this ingredient to a 'high-purity Psychic Essence Solution'.
The former is rare and expensive and, as the name implies, can ensure a certain growth in the physical quality of those who take the potion, even nourishing the soul to some extent.
The latter is quite common, for Ian could extract a bottle himself from the sap of the Redwood Forest tree cores, obviously not as precious as the former.
However, it would still allow a person to advance to become a Fae.
