Nixies

Nixies are a hostile race of sea-dwelling humanoids which appeared in Ultima IV.

Description
Nixies are said to be descended from the elves of Sosaria, and appear have to outlived their more peaceable cousins. While they appear to have been a sapient species capable of speech, little is known about Nixie society or culture - given that almost all of its interactions with mankind were violent. Known to frequently harass and attack human travelers at sea during the early Age of Enlightenment, these aquatic beings were often seen in the company of giant seahorses, and would harry their targets by hurtling their long tridents at them from across the waves.

Nixies were not sighted by human travelers after the Avatar's first quest in Britannia, having either gone the way of their elven cousins or contenting themselves to remain unengaged with the realm's land-dwelling races.

Notable Examples
