The Last Dreamkeeper

Elara's ordinary life as a city archivist is upended by impossibly real dreams of a moonlit forest and the terrifying shadow creatures that lurk within it. When these entities begin to cross into her waking world, she discovers a hidden legacy: she is the successor to the Dreamkeepers, ancient guardians who maintain the Veil between reality and the world of dreams. Guided by the spirit of her predecessor, she learns the balance between worlds is collapsing.
A vast, intelligent enemy is harvesting humanity's abandoned dreams and weaponizing them to fuel a global nightmare. To fight back, Elara must embrace her powers and undergo a profound trial that tests her against her deepest fears and regrets. Her journey culminates in a descent into the enemy's stronghold, where she confronts the shocking truth: the antagonist is Lycander, the first Dreamkeeper, who has become twisted by despair over humanity's failures.
Believing hope is a sickness, he seeks to bring about a silent, dreamless peace. In the final confrontation, Elara makes a choice not to destroy him, but to heal his web of despair. This ultimate act of creation requires the ultimate sacrifice, forcing her to give up her mortal life to become a permanent, divine guardian within the Dreaming, saving a world that will never know her name.
