Normally we stick to 3.5 here, since that's the edition we count as "ours", but I was already aware of the Raven Queen and when picking out gods for this month I got a really cool idea for her. It was eventually developed into this. She seems to be the 4th edition replacement for Wee Jas as the impartial but scary death goddess.
I like non-evil death gods. It's really easy in death-fearing, Judeo-Christian world to assign death gods to a Satan-like role. But it's more intersting when they're not evil; they're there as guardians, because death is inevitable and someone needs to make sure its administered with balance and fairness. Take the joyful Death of the Endless, or Hades of Greek mythology. Hades seem to get screwed over in modern adaptations, often being put in a scheming, evil, demonic role (see Disney's Hercules or the 2010 Clash of the Titans). In the myths I've read, he was always a scary dude, but one of the nicer, calmer gods of the pantheon (relatively, of course).
