It depends on the breed. The high elves are particularly magically attuned and fair skinned, while the common elves look a bit closer to humans. Dark elves are dusky, brown skinned and more swarthy in appearance, and the syrium, who are like the elves but not quite the same, have a very long ear and a gray, almost ashen hued skin with a bluish tint. They're not quite as long lived as the elves are, though elves live longest when close to their magic.

Ghosts ... I think are part of this world being a nightmare. The child whose dreams we inhabit was probably raised on ghost stories, so there are ghosts here.
