As they travel, Letty, Diaria and Nell encounter Nashim, a jinn and tax councelor of the Non-Human Internal Revenue Service. With his exile, Letty is considered an independent and is required to turn in an annual tax report, making his need for a new home and steady income all the more urgent. Nell decides to let Pip choose their next destination, which turns out to be a Hero training dungeon beneath the kingdom's capital city. With the dungeon being closed on a "day off", Nell impulsively starts exploring it; she and Letty get lost, and in their efforts to find an exit, they end up within the halls of Nell's former home - the royal palace itself!
