There's a difference between Death and Destroying the Universe. I haven't seen the PHB of course, so I don't know what kind of death god the Raven Queen is, but I would imagine her being more of a "Everything dies sooner or later, and when it does it's mine" type. The Primordials on the other hand want to destroy the universe, including whatever place dead souls go to - a clean slate.hong said:Actually, if there's any god who should be connected to the Primordials, it's the Raven Queen IMO. And no, that doesn't mean she should be evil or chaotic evil; it's because death is a concept that should be so timeless it predates even the gods.
I can't help but think of Pratchett's Discworld, where Death is a rather positive figure (well, not viewed that way by most inhabitants, but from the perspective of the reader) who really doesn't like it when the world gets messed up by things from the Dungeon Dimensions and the like.
