Light elves are a self-given denomination of Elves, in opposition of the Dark Elfs.
Often "Light Elves" only includes the various light skinned races of the Rossnes category of elves. Although, skin color might sometimes be 'warm' but still tanned, rather than 'dark'. Anqueael Elfs might have milky white skin, but are still considered 'Dark Elfs', in part, due to the 'cold' and 'colorless' nature of their pale skin.
Additionally, the Northern Snow elf is also usually considered a Rossnes Light Elf due to having some Rossnes traits and cultural ethnicity to related light elves, even though they can be rather dark skinned, and sometimes having a 'colorless' greyish skin tone as well.
Sometimes, for political reasons or certain arbitrary reasons of categorization, the list of "Light Elves" might expand greatly. The Anqueael Elfs, Verdennos Elfs, Darhake half-breeds, and some groups of Flairie elfs of the Zuleis category might be found on more expansive lists of "Light Elfs".
