In Thelpousa in Arkadia Demeter had the title Erinys (the Wrathful One). She also had the title Lousia (of Washing. I took the liberty to change it to the Purified One in my comic since it sounds a bit better). The Thelpousan cult was closely related to that at Phigaleia, also in Arkadia, where Demeter was known as Demeter Melaina (Black Demeter). In my comic I have made these two cults into one.
It’s a ruin, he has his fathers hair...err. Mane.
