Grim Countries
Where changelings come from, what forms them, how they're born and why are the biggest questions any changeling might ask the world. However, it is a question without an answer. Many mortals of the Grim Countries consider them to be cannibal child thieves that steal babies from the cradle, devour them and take their place. No one can verify this claim, but it persists nonetheless. Changelings, by contrast, mutter among themselves that in Otherworld there is a place where changelings are born and welcome, although no one knows if this place exists. Such a place, were it to be real, would be salve to the collective changeling soul.
The Psoglavi of Etomesto believe that Changelings are Vardyvle and should be ignored completely. However, in some cases the Skollomanse will gather Changelings up and have them brought to the Skollomanse directly. What happens to them afterwards is unknown as none ever return. While this sounds horrific, it means that Etomesto is the safest country for Changelings to hide in, if they like those odds.
Riven Lands
In the Riven Lands any Changeling born to Fomorii is destroyed without question upon discovery. However, its also known that they enslave Changelings from time to time for use as spies. Fomorii believe that whenever a Changeling takes your shape, it takes a great portion of ones' power.
The Ordovic are loathe to hate anything as a monolith, but even they relate myths from when they walked out of the ocean. Myths of eggs spawning strange offspring. Legend says that in the early hours, Changeling offspring whisper to their siblings and lead them into the jungle where they are snatched up by the huakaʻi'pō, or Nightmarchers, and carried away to the realm of spirits.
Symerans, however strange it may be, do not have legends or stories of Changelings haunting their hearths and eating their children. However, they believe that Changelings are poorly developed offspring that have an unfortunate birth defect. As they are not Symeran in their "real face" they are forbidden from most Symeran culture, even forbidden from entering the ranks of the Rahlamaan.
The Rekiret believe that Changeling children are the descendants of, or corrupted by, the evil goddess Espet. For this they are regularly purged from the Qishemi.
Scorched Realms
Across An Mhuir Thoir and past the Wandering Isles in the land of Djinnaya, the life of a Changeling is one haunted by fire. The Kitajal-Jinn believe that Kitajal-Ol offspring who are "tainted" by the Changing Curse are in danger of spreading it further and wider. To prevent this they gather the Changelings, capturing them if need be, and dragging them to the Mazar of Nariil & the Scripture of Flame to be cleansed in holy fire. This has the side effect of ridding the world of the gathered Changelings, as well.
In Samara Strima the Kitajal-Shan have a different method of dealing with their Changeling population. The imperial soldiers gather any known Changelings and bring them to Empress's court where they are experimented on and dissected by the Order of the Driven Nail.
The Kitajal-Ol are no more innocent than their uplifted brethren. Ol believe that Changelings are "Matunda Mabaya", or bad fruit, that fell from the Vila Tree and poison the world with their existence. Moreover, the Ol say that it was the Changelings that tricked their spider-god into tricking their alfil-god into shattering the world during the Sundering.
Across the waters of the Bay of Teeth, the island nation of Kinokashima rests. Here, it is actually the Changelings who tell horror stories to their young about the Kitsune (Cáo Tinh). Changelings avoid Kinokashima as it is said the kitsune there have the ability to see through the glamour and disguises of Changelings, but only ones with a certain number of tails. The problem is no one knows how many tails are required, so the island is avoided.
