so figured I'd "go deep" on this one and see if there was anything. the closest i can come so far to anything of the sort is Izanami(wife) and Izanagi(husband) who gave birth to the Archipelago of Japan. these could be a parallel to Lord Rak'Ashiir and Queen Nah'Ashiir and the founding of Torsis, the original name for CoM. When Izanami died, Izanagi traveled to Yomi, the mythological Japanese underworld to retrieve her, only to find her rotting away in the land of the dead. Following this Izanagi went into a fit of rage, blocked access to Yomi with a great boulder and further created a couple other shinto deities.
also there is mention of the Amenonuhoko- the Heavenly Jeweled Spear which was given to them by the old gods to help them form the land. this could be where the inspiration for the Spear of Fate shaman epic comes from. Since Rak'Ashiir is the final fight kinda makes sense.

Like i said before. the japanese word for mist is Misuto which is borrowed from english/german roots. I know the japanese got their word for "work" arubaito from the germans during WW2ish so its possible this is another borrowed word from that time in their histories. Japan has two alphabets. Katakana for borrowed words from other languages, and hirigana for their own. the name CoM is probably just the writers and devs coming up with a clever name for the city from Yomi and the japanese fable? anyways thats all i got.
