A large, couch-sized emerald from which all elven life supposedly sprang. By chipping off a tiny shard and inserting the shard into an otherwise normal elf, the elf will transform into an elven subrace. Sun elves, moon elves, ghost elves, wood elves, high elves, wild elves, poop elves… all elves aside from the basic elf were created in this way. It is said the Elfstar was created when Corellon Larethion had to poop, and held it in for a really long time until it got impacted, and when he went it ends up it had been pressurized into a gemstone. The Elfstar also seems to be able to make other elves insane with prolonged exposure.
