The Yggdrasil Forest

The Yggdrasil forest is the forest where elves are born and raised, such as Zoey. Its name comes from the World Tree in Norse mythology, also known as Yggdrasil. It is a forest of very large trees, which are never cut. Zoey took Levin and Malachi there and raised them for a few years. The trees there are sacred and have been mentioned to be able to absorb dead elves' souls after they die. It has been mentioned many times in the series, but as of Season 2 ep 14, the viewers have never been there.
