Somniva
Created by the Goddess of Dreams Unysta, Somniva is a realm in the Afterworld characterized as an endless starlit forest where many calm souls go to rest and dream. Somniva is inhabited by Dryads , Wisps and the many spirits of nature who also serve as its protectors and caretakers, tending to the infinite gardens that grow across the realm. Furthermore, during the Battle of the Wilds, the God of the Hunt Fenros allied with Unysta to punish the barbaric Humans that raided Gwynbrenon by transforming them into wolf people and locking them within the dreamworld as servants to the Dryads, in the process creating the Wolfen.
Though Somniva is a Death Realm, it also serves as the place where the souls of the living go to in their sleep, seeing wonderful and often times otherworldly sights before they wake up again.
The Gate of Dreams, which is safely located within the heart of Nytlerei, serves as a direct gateway between Auria and Somniva though only Dryads and those they choose may pass through it.
Although Somniva is a place of peace and solitude, it is also in constant danger of the Nightmare, a place of darkness from which eldritch monsters spawn to attack the dreamworld with reckless abandon, seeking to fully corrupt the infinite forest with horrific visions. Lifeforms who fall asleep and wander into Somniva to rest may instead be at risk of seeing the Nightmare and it is the sworn duty of the Dryads to protect these souls from being bothered by the evil by guiding them to the right place as well as battling the Nightmare the best they can... however sometimes it simply is not enough and some mortals do suffer the curse of the Nightmare in their sleep.
Somniva has raised many questions from the mortals who regularly have their subconscious traveling there during their sleep. The knowledge of the Gate of Dreams as well as the Dryads has made them question what the realm is truly about and what dangers it may pose but nobody has yet been able to truly understand it. High ranking Elves who have earned the trust of the Dryads are gifted with the knowledge of the dreamworld as well as the Nightmare but have sworn to also keep the secret from reaching the public, only aiding the living world by passing on teachings that push for meditation to strength people's sanity to combat the Nightmare when it tries to grasp them.
