I played fantasy games alot, and Forgotten Realms in particular, many dieties there are nice. Lathander is alot like my character in fact as are other dieties. This is not a real world mythos game if you want Greek dieities I'd play one as a Greek diety but if we are making up our own and its not adult in nature why can't I take a diety that is nice to mortals?
I thought she would be nicer opposition than the goddess of dark evil bad things that controls hell or something, one that is good to mortals in a way that might tick of other deities when she meddles to help them. At least the commoners and those yearning for freedom in various forms. With an end goal she wants and even she is not sure how to get there yet. As a player I have ideas as a deity she is going to have to keep things simpler for now.
