Well, Persephone ,she is a symbol of rebirth and death. A lot of the myths speak of her as sweet and kind but also seem to fear her sometimes so I was playing with the idea of a split personality but not sure if I will go with that yet or not. I'm not even sure I will choose that goddess yet or the other one...maybe I will do both.

As for Nyx, she is one that even Zeus slightly fears so she is definately going to be serious and maybe a bit cold. Now she is also a guider and helps people with how ask to help with their suffering by helping them to accept the darkness they have in their lives as well as ask for forgiveness from those how have wronged you or those you have wronged. So she is nicer than she seems but mostly not one you want on her bad side. I will probably going to play with that a bit of I choose this goddess. We will see. Haven't played much with ideas yet
