The Toybox Citadel is a small project featuring the unwilling reality-traveller Thayne Sullen, a 46-year-old washed-up and burned-out father searching a magical toybox for his missing daughter. Trapped in a world sculpted entirely from her rampant, six-year-old imagination, Thayne is struggling to grapple with the new rules of living, surviving, and most importantly, the whereabouts of his only joy in life-- his daughter Chrysanthemum.

After an arduous journey across forests of cotton candy, musical forests, stuffed animal kingdoms and building-block castles, he makes his way into the stars to meet with The Auditor, a godlike entity that exists within the Toybox, and the instigator and reality-sculptor bringing all of Chrysanthemum's narratives to life. This all-knowing being surely must know where Chrysanthemum is, right? Surely this moonman can bring her home, right...?

Or are his intentions truly darker than being a vassal of a child's boundless imagination?
