 This unique concept makes it a sort of reverse-Bangsian fantasy, or rather makes our world its Bangsian fantasy.Mankind shares this world with other intelligent beings, like the serpent people of Beraoti, the beast-men of Komilakh, the silvans of the mountain forests, and the mermen and mermaids in the sea.The fauna is largely that of Earth's Ice Age, while the vegetation is similar to that of present-day Earth.
