The Rieklings are creatures inhabiting the colder northern and northwestern regions of Solstheim. They have blue skin and sharp teeth; they're very short and are known to ride tusked bristlebacks as mounts from which they cannot be separated, even in death. One notable weapon used by Rieklings is the Riekling Spear, which appears to be the head of a wolf punctured by a long sharp pole.
Many Nords in Solstheim would mention that they believed the Rieklings to be descendents of the Falmer. In Skyrim, it was revealed that Skyrim's Falmer retreated underground and degenerated into a primitive, feral state as a result of poisoning by the Dwemer and long years of conflict with them. It still remains possible, however, that Solsthiem's separate population of Snow Elves did indeed become the Rieklings.
