The Leviathan returns as a Haunted space, Calus's ship now permeated by Nightmares, the Season of the Haunted using the Crown of Sorrow to force Guardians to confront what they have been avoiding. The Traveler shining on all is the City's theology. Not everyone reflecting it back is the season's complication — Caiatl, Crow, Zavala all carrying something that the Light cannot simply illuminate its way through. The season is about what you do when the Light reaches something in you that has learned not to reflect.
