Persephone (unofficial)

Persephone is the wife of the Lord of the Dead (unofficial) and the daughter of the goddes of spring (Ceres most likely).

Behind the scenes
Persephone originates out of Greek myth.

In the official lore, KQ6 and related material, the land of the Green Isles is said to be tropical and have the single season of spring. TSL suggests that the land has all four seasons, and that Spring and Summer take up half the year.

In KQ lore, if Persephone existed she would likely be the wife of Pluto/Hades rather than Samhain (there are multiple lords of Death in KQ lore).
