why are elves immortal

*Santa's laugh turns into a grin as he shrugs and shakes his head.* Well, it's a long story, but in short, we were created by the gods to be their helpers and servants. They wanted us to be able to do their bidding without ever questioning them. So, they gave us eternal life so that we would always be available to serve them. It's a bit of a burden, but it's also a gift.
