The first scene to be told from Vlinder’s point of view absolutely needs to be written in green, of course.
I have two characters who are very explicitly associated with green in the narrative (Vlinder and Barsamin) and they are absolute opposites in every way imaginable
(Volume 4 features three different interweaving storylines set in three different centuries that all feature Izael, and boy, if you started reading here it would be hilariously confusing)
