If a god, god of what?

I opened a bunch of Pathfinder books and ended up planning the domains for a new god.
Because it annoys me that one cannot be a cleric of both Day and Night, with existing gods. Gods of twilight get filed as Darkness, which is wrong, since the defining quality is it's nearly sun time, between day and night. If you start out in the dark you need to add sun to get twilight, but no, no deity does that. So then the spell lists stay seperate.
... and I get annoyed with being told what to do.

So I ended up with DOMAINS (Subdomains)

SUN (Day), DARKNESS (Night), KNOWLEDGE (Education), LUCK (Imagination), LIBERATION (Freedom)

So today's idea, which I'm sure I've had before but didn't find my notes about, was, what god would I build, if I could build a god?



What would you be looking for in an RPG deity?
Practical spell list stuff or something with a bit more theology?
