Nimue
Dark Lord
This lore is written from the perspective and the knowledge of the men of Ysgard, and so is narrow in scope, and may be incorrect on the details of the wider world. Names are in the common tongue of Aerde, while names in italics are in Old Ysgardur, which only wizards and scholars speak, and is closely related to the elven tongue of Yvaldri.
The most numerous, diverse, and adaptable of the races. Magical talent is rare among men, and must be trained with years of study. They live to be 60-80 years old, although witches and wizards can live as long as 200 years.
Elves - Alfar
Slender and slightly taller than men, with pointed ears and angled features. Almost all elves possess the capability to use magic, though some are far more powerful than the rest. There are fewer differences between male and female elves, as male elves cannot grow beards. Resistant to disease, they need to eat and rest less often, but are more susceptible to poison and toxins, and strongly affected by magic, both harming and healing. They have children rarely. Elves live to be 250-300 years old, and those strongest in magic can live as long as 450 years.
Dwarves - Dvergar
The least numerous of the races. Very short, stocky, and muscular, with long hair and beards. Resistant to magic, poison, and physical injury. There are greater differences between male and female dwarves than with the other races--dwarf women are shorter, curvier, and much less hirsute. Magical talent is extremely rare among the dwarves and may never get trained in those who have it. Dwarves live to be 100-140 years old, although those very few among them that can use magic may live to be 200.
Halfbreeds
Elves and dwarves cannot have children together. Half-elves, half-men take most after their human blood, save for a tapered point to their ears, and an increased likelihood for magical talent. Roughly a third of half-elves can cast magic. They do not inherit the full swiftness of their elven parents, and tend to be more susceptible to sickness and spells. They generally live to be 120, or as much as 280 if they are strong in magic. Half-dwarves, half-men, often called halflings, take most after their dwarven blood, and are almost as short as dwarfs, but less stocky and without their hairiness. They are hardy and somewhat resistant to magic, but are disparaged by dwarves for their perceived weakness. They live to be around 90, or as much as 160 if they cast magic.
