Road Less Traveled mostly focuses on The Midnight (my interpretation of Nightcat). The Iterators are a sort of side story.

Years after the tragedy that shaped her, she settled into the slugcat colony that resides in the Outer Expanse. Her life is peaceful, looking after the pups in Gourmand's absence.

One day, a fluffy green slugcat appears in the colony and starts helping out the best he can with his pacifist nature and knowledge of things beyond their understanding. Midnight's confrontation with the green slugcat takes her on a journey to find answers (and family) to assist the curse that plagues her existence.

Five Pebbles somehow found the work around for a taboo that prevented Iterators from tinkering with their puppets. In a bid for freedom, he incorporates The Rot into his puppet and dresses himself for adventure.
