When a mortal makes a deal with hell and sells its soul, the demon responsible for the bargain tears out a shard of that person's soul and reshapes it into a quasit. The quasit assist the one who sold his or her soul, which it is bonded to. When that person dies, the quasit makes a final journey to Hell with the soul, before dissolving and allowing the two to become whole. This has the added benefit, for the devils anyway, of circumventing much of the afterlife's bureaucracy. Instinct: To bring its bonded soul to Hell

• Turn invisible
• Inflict shakyness with venom
• Usher the bonded soul to Hell
