Angiaks
An angiak was a child of the living dead in Eskimo lore. These are created during harsh times when an unwanted baby is taken out into the snow by a tribe's elders to die of exposure. Unless the tribe moves on to another hunting ground, they may soon find themselves haunted by this small, miserable ghost.
Each night, it returns to strengthen itself by suckling at its mother's breast, and when it has gained enough strength, returns to wreak its revenge on the elders. If it is absolutely necessary to dispose of a child in this way, one must foregn naming him before his death, as a human acquires a soul only after gaining a name.
