Oh dear, that will be fun. I don't really need a CS for Hades, do I? If he becomes important later in the story I'll write one, but I tend to do my NPCs as rather freeform.
Hypno is very shy, yet a young child like god but....him and thanantos do not have very good relationship as you can tell that Hypno was loved by his parents while his brother thanatos was not liked and went to the underworld with hades.
I even had an idea with Erberus and Nxy coming to see Hypo and how he is doing and still disowning their own other son thanantos and some drama happens between father and son
Oh dear. That would be very cool, in a terrifying "Oh my gods I'm surrounded by four feuding immortals and how in all Olympus am I not dead yet?!?!" sort of way.
Yeah well she could talk back to erberus which cause a big fight with erbetus and thanatos. Ending with thanatos getting extremely hurt which pisses Hades off that erberus would hurt his adopted son
And then, even though Thanatos is immortal and so would automatically heal himself, Maria can freak out and go all medical on him. Hehe. Oh, that will be fun. I'm guessing it will happen during the Festival of the Dead?
