Sparafucile is a Smoke Knight, attached to Princess Xerxsephnia von Blitzengaard, who first puts in an appearance as the latter woman is urgently and mysteriously plotting to get in contact with Agatha while said gal is in England. (Though her name is not revealed until her .)
She appears, based on skin color and forehead decoration, to hail from the Indian Subcontinent. She also sports a general skull motif with her clothing and accessories, and () appears to have pure white eyes.
Her initial function seems to be to Loom Ominously in Mr Quinster's general direction as Seffie assigns this England-based minion various impossible tasks, such as getting the two women into the sealed undersea dome of the Queen's Society. After Quinster somehow manages this, Sparafucile kidnaps Agatha during an unguarded moment and brings her to where Seffie is waiting.. with, it turns out, her ailing brother Tweedle, who requires Agatha's physical touch to not die.
Despite going to all this effort to save Tweedle, she later cheerfully reassures Tarvek and Gil she has absolutely no problem with them punching him hard in the face. She also mentions that she in college, in order to perfect her technique, while that some of the crazy stuff Sparks have told her over the years might actually be true.
Varpa, another of Seffie's Smoke Knights.
