The Primordials once sought to turn the Solar Exalted into their puppets by seducing them with their eldritch power. They forgot that everything in Heaven and Earth belonged to the Lawgivers by right.
You now have access to all the abilities and Charms of the Primordial's modified Solars, the Abyssals and the Infernals, without the negative effects such cursed tools usually bring (such as Urges or Resonance).
This includes the Charms of the Broken Winged Crane, as the purity of the Solar's conviction turns the blasphemous, Luciferian act of overturning the Gods and Primordials to become a Devil-Tiger (a half-Primordial, half-Exalted being), into a heroic and noble theft of the Promethean Fire.
