The Autumn Kingdom: The Wraithbound Queen (2026-)

The Autumn Kingdom, a fae realm previously documented as fictional by their father, is confirmed as the location where the parents of Sommer and Winter are held captive. A military force composed of goblins, trolls, and transformed human captives guards the final barrier to their objective. The sisters' primary operational goal shifts from initial discovery to a tactical incursion, with their father's liberation contingent upon breaching this defensive line. Their journey has permanently severed their connection to the human world, framing the conflict within the mythological borderlands' own logic and hierarchies.
