“'Alabestrine is what we call a solo star...' 'Are there a lot of those?' Sophie asked. 'Millions, no idea why this one would be special.'”
Alabestrine is a solo star, meaning it is separated from the other stars. Because of this, its light is known as "pure light," unaffected by other light around it. Alabestrine is related to the Initiative Symbol and the Initiative that allow the Neverseen to move from hideout to hideout. It is currently unknown why the Neverseen chose the stars that they did, but all of them are Solo Stars.
