Given that a Vulcan is a regular at the
Elf Only Inn, but so are a clone of Duke Nukem, a "deamon", a tentacle monster known as "the eternal sweeper" and a munchkin from DBZ; nothing conclusive can be extrapolated.
IMC, there's three cultures of elves: the barbaric (N, living in forests, over-emotional, fickle, as likely to frolick with a traveler as they are to hunt him and feed him to their wolves -- or sometimes even to themselves), the civilised (CG, sea-going, avoiding most other civilisations but always behaving friendly and politely when they meet other people), and the decadent (LE, living in the cities they rule, ruthless oppressors who masquerade as divine beings).
The only thing that would be essential is the grace. They are always lithe and dextrous. Not necessarily beautiful, though, with their sharp, angulous features, they can look somewhat insectoid... Look at some pics of Mialee, you'll see what I mean.
Pointed ears? D&D elves have, but then again, lots of races have pointed ears in D&D. Magic? Ah! They wish! Gnomes have magic, but not elves. The only contender in magical elfdom are the Drow -- who conveniently don't exist IMC!
