DreamTale is an alternate universe (AU) within the Undertale fandom, created by JokuBlog. The story revolves around two brothers, Dream and Nightmare, who were once guardians of a tree that bore golden apples, symbolizing positive feelings like hope and happiness. Here's a brief overview of the story:

The Origin
Dream and Nightmare: The two brothers were created by the tree itself to protect its golden apples. Dream was kind-hearted and pure, embodying all positive feelings, while Nightmare absorbed the negative feelings that came from people's fears, anxieties, and sorrow.
The Conflict
Over time, Nightmare began to suffer from the corruption of the negative feelings he absorbed. The villagers started to favor Dream over Nightmare, leading to Nightmare's resentment growing. The negativity twisted him into a dark version of himself, eventually turning him into the antagonist of the story.

The Fall: Nightmare eventually snapped and decided to eat the golden apples to gain power. The villagers, who once scorned him, fled in terror. In a fit of rage, he attacked Dream, and a battle ensued. Despite Dream's attempts to save his brother, Nightmare became a being of pure darkness.

The Separation
After the battle, Nightmare was banished from the village, and Dream became the sole guardian of the tree. Dream continued to protect the remaining apples, while Nightmare roamed the world, spreading negativity and seeking to corrupt as many souls as possible.
The Ongoing Battle
Dream and Nightmare continue to clash throughout the universe, representing the eternal struggle between positive and negative emotions. Dream seeks to protect the world from his brother's influence, while Nightmare aims to plunge everything into darkness.
DreamTale explores themes of duality, brotherhood, and the impact of emotions on one's identity. Dream is often depicted as a hero, while Nightmare is portrayed as a tragic villain corrupted by the very emotions he was meant to protect others from.
