My interpretation of Corellon Larethian, god of magic, spring, beauty and art, as he was presented in the D&D campaign I'm playing in.
Our characters has been spending a lot of time collecting a set of artifacts with a connection to four gods, Corellon, Sehanine, Raven Queen and Pelor, I had a hard time figuring the connection between the gods, I won't spoil it for you though, let's see if you can figure it out yourself ;)
Anyway, the party discovered that to activate the artifacts they had to ask the gods for their favor. They approached Corellon first, expecting having to perform a difficult task or something to prove their worth. They were quite surprised when he just decided to activate the artifact, throw a party and convince Sehanine to give us her blessing for free too. I'm going to attribute that to my character being an awesome paladin for him and praise the fact that they found him in a good mood.
I do enjoy the way our GM plays him, as a weird flakey god that despite his vast intellect and knowledge, seemingly acts purely on emotion and impulse.
