There are many different interpretations of elves out there. I'd like to hear some of them.

Here is my version:
1. Elves are Fey, not Humanoid.
2. As fey, they have a special connection to nature/mebhaighl and are able to use true magic.
2a. They still have to be blooded to use battle/realm magic.
2b. Their fey nature makes them especially well suited to druidic magic, although they are not limited to it.
3. As fey, they are unable to worship gods/the gods are unable to be worshiped by them.
3a. They didn't worship Azrai, but were seduced by his words.
4. When they die, they just return to the elements.
4a. No afterlife. No ressurection or raise dead either.
