Annwyn

The Dark Realm of Annwyn is one of the nine Dark Realms, which are a group of evil dimensions unreachable for the mortal beings of Rathnir. Annwyn is known for its pursuit of knowledge in the arcane.

Origin
It is unknown how the Dark Realms were created, but some assume they were created as soon as the first light started to illuminate the universe. Once there is light, there is also darkness. Annwyn is, like the other Dark Realms, protected by a barrier of unknown and ancient magic, making it unreachable and inescapable. It's said that only mortal beings outside of the Dark Realms are able to gain entrance, but only with the help of a creature of one of the Dark Realms. Annwyn is a place where the laws of nature are twisted and the very air is suffused with tales of nightmares. Like in the other Dark Realms, 100 years in Annwyn are just one hour in the mortal world.

The Annwyni
In this realm lived creatures unlike any that had ever been seen before. They were the Annwyni, vicious-looking beasts with sharp teeth and claws, but despite their fearsome appearance, they were a peaceful people. They were a society focused on knowledge, studying all manner of arts and magic, including the darkest and most forbidden forms of sorcery. But their obsession with power and knowledge came at a great cost. As they dove deeper into the mysteries of the universe, they lost touch with their own society. They became cold and calculating, more interested in the pursuit of knowledge than in the well-being of their own kind. The Annwyni despise war and any other type of conflict that might interfere with their studies. They had long forgotten the meaning of betrayal, and they saw no harm in sharing their secrets with those who sought to learn from them.

Demise
For centuries, the Dark Realm of Annwyn remained isolated from the rest of the Dark Realms, a place where the Annwyni could pursue their studies of dark magic without fear of outside interference. But one day, a mysterious figure appeared in the realm by the name of Kaiba Aelarion, and he claimed to be a wanderer from a distant realm who had stumbled upon the Dark Realm by chance. At first, the Annwyni were suspicious of Kaiba. They had long been isolated from the outside world, and they were wary of outsiders who might seek to exploit their knowledge of dark magic. But over time, Kaiba gained their trust. He claimed to be a scholar of the arcane, and he spent many years studying alongside the Annwyni, learning their secrets and earning their trust.

Over the course of 400 years, Kaiba worked his way into the inner circle of the Annwyni. He became their trusted advisor and confidant, and he was privy to all their most closely guarded secrets. But all the while, Kaiba was plotting his own agenda. He was fascinated by the power that could be wielded through the use of dark magic, and he sought to harness that power for his own purposes. Slowly but surely, Kaiba began to manipulate the Annwyni. He sowed discord and mischief between them, whispering half-truths and lies into their ears to turn them against each other. He knew that if he could weaken their minds enough, he could easily control them and use their knowledge of dark magic for his own purposes. For over 100 years, Kaiba played his game, subtly manipulating the Annwyni and twisting them to his will. And then, when the time was right, he struck. He betrayed the Annwyni and cast a powerful curse that drove them mad with rage and made them turn on each other. For centuries, the Annwyni fought among themselves, tearing each other apart in a frenzied frenzy of blood and magic. Kaiba watched from the shadows, content in the knowledge that he had succeeded in his plan. Eventually, the Annwyni went extinct, and Kaiba was left as the sole ruler of the Dark Realm of Annwyn. The Annwyni never got to know what Kaiba's real intentions were.
