Within the Elvish Isle there is a dense forest that is sacred. It has no direct connection to any known God but it’s treated like hallowed lands. It has no protectors or shrines. You will not find any signs or elvish tour guides. No elvish lord claims ownership over the lands.
Many people have been lost while wandering into the forest. Some return months later, claiming to have only been away for a few hours. Others are never to be found again. It’s never implied that the forest is a dangerous place but those who know would never dare to enter the forest.
