Ravenloft is the Domain of Dread, where hundreds of people have been taken from various cultures. The realm is filled with many Gothic Horror elements from various cultures, and over the years some Asian influences have appeared as Island of Terrors. Likewise a on a Gothic Earth, where the dark Powers have influenced history, an Asian theme supplement was also planned.
I'cath has been identified as an island of terror. It is a small forested domain in which travelers usually find themselves lost. The weather is usually heavy with thunderclouds, threatening a storm. As they wander some of the travelers encountered Chinese-like small mansions, inns, or beautiful tea shops often run by beautiful women. Travelers who stay at such places may find companions missing, structures disappeared, or worse decrepit structures.
The Truth behind this is the forest is cursed. On the world of Toril, a powerful sorceress known as Tsien Chiang from Kara-Tur and her daughters were taken by the Dark Powers for murdering one of their own. Tsien Chiang has a hatred of men, one which she passed on to all but one of her daughters. She had used her daughters beauty and charms to lure many men to their deaths and drain them for her own personal gain. Yet, her daughter Nightingale was appalled by her mother's plan. When she and her lover failed to stop her sister's and mother, Nightingale was killed. I'cath and her daughters continue to prey on travelers lost within their domain, and Nightingale resurrected does her best to be an obedient daughter by luring the wicked and letting the pure of heart go free.
The second such site is a larger domain found on a raised island chain in the Poisonous Sea. These island are known as Rokushima Taiyoo and are ruled by the Shujin, the son of Shinpi Haki a great Warlord who ruled over these islands. He was a ruthless and cunning warlord that tamed the islands by any means necessary. When Shinpi Haki died, his began fighting for control of the lands. It was then that the mists rolled in and a great earthquake happened. When the mists cleared the entire chain of islands were raised above the sea. It was soon discovered that the surrounding seas were toxic in nature, and that they were cut off from the rest of the world. Soon each brother began blaming one another and each went to war with each other. When one of the brothers fell in death, their island was pulled down into the sea. The island chains again experienced another great earthquake and adjusted itself. The people here a very Japanese like, during the feudal era. They are distrustful of outsiders, as it boggles them how some could have traversed the poisonous sea or managed to climb the deadly cliffs.
Like other domains, the truth of this curse is hidden. Shinpi Haki was a ruthless warlord who was without mercy or honor. He seized control of these islands. His only pride and joy were his children and the legacy that would live in. When he died, the Dark Powers confronted him, but Shinpi Haki was a stubborn should who accepted his fate for the life he lead and had no remorse. So the only way the Dark Powers could torture him was through his family. He children had learned and followed in their father's footsteps. They instigated the feuds between the brothers, and let them tear Shinpi Haki's legacy apart. Helpless to warn his children of save his legacy.
The last area of Ravenloft was to be Gothic Earth, and focusing on who the Dark Powers influenced parts of Asia. Dr. Fu Manchu was known as one of the agents of the Dark Powers, and his organization spread corruption and terror of the Asian Continent.
