In Icelandic mythology, Trolls were a race of cannibalistic giants. They appear in various Northern mythologies. In Norse mythology Trolls are represented as a type of goblin, stumpy, misshaped, hunchbacked dwarves who live in mounds and hills, inclined to thieving and of substituting one of their own for a human baby.
