they're gray-skinned elves with white or silver hair and red, gray or blue eyes.
They mostly live in their own nations or settlements or mixed with light elves and humans. Some also live in the colonies mixed in with brown elves.
Like the other elves they live for about 250-300 years. They have, like the light elves, a lot of shared history with humans since the three races look and behave similar enough to cooperate
