Elves are creatures of light that appear in Norse mythology. They come from Alfheim, which is one of The Nine Worlds that are held in the branches and roots of the world tree Yggdrasil. Their lord is Frey, father of Magnus Chase. This world or realm is mentioned in The Sword of Summer, and appears in full in the following books.
Elves are one of the three mortal races. They look like humans, but they need the constant sunlight, like in Alfheim. Without it, they need sleep and will eventually fade away and die. They look much like humans but have a few non-human traits. These traits include pointy ears, green veins, and reflective eyes. They also smell like pine needles and wood smoke.
They have become much like humans, losing connection to the other realms and magic. Elves were once skilled magicians and archers. Nowadays, many elves spend their time watching "funny pixie videos". Many elves also that believe Midgard is a myth; they think humans still wear tights and live in medieval castles. Elves do not have much tolerance for things that aren't perfect, including their own children (as evident in Hearthstone's case).

- In mythology, there are two types of elves, the Lyosalfar (light elves) and the Dökkalfar (dark elves). Light elves are the ones most likely featured in the series as they have fair skin and hair and thrive on light, while dark elves live underground and have skin said to be blacker than pitch.
- According to Alviss, the elves call the sky, "The Fair-Roof."
