Ice nymph

The Ice nymphs were a race that was similar to the Island nymphs that lived in the Second Age until their mysterious disappearance in the Fourth Age. They were said to be a little different from the Island nymphs, for their skin was not purple, and was a sapphire blue due to living far in the north. They were the only permanent humanoid species to live in the Northern Lands, since their bodies adapted to their environment. They were mostly hunters and gatherers who lived around the area which is now called Arqspra, mostly in small villages.

However, it was confirmed by Historian Minas that they actually had civilizations up in the north, ruled by a unique system of government called Democracy, where their leaders do not have the power, and instead, it's run by the people and the councils they lived in. Their chiefs were called Presidents, and they were elected every fourth of a year. Despite the fact that the Ice nymphs are mysteriously gone, humans still study this "Democracy" and will possibly use it far later in their society.

Like Island nymphs, Ice nymphs are a bisexual race that believe that their hearts should match their love, not what gender they are. Ice nymphs though, are not matriarchal like Island nymphs, so men also had rights in their society. Both genders can carry the same rights to land, fighting and running for political office.

Trivia

 * The Ice nymph's idea of Democracy appears to reflect on real world Democracy, where their leaders and chain of command is elected into office, and run for a certain number of terms.
 * Ice nymphs are the only humanoid race that mysteriously vanished on RuneScape.
