Remember, in a fantasy setting a magical elven race can still be dark-skinned because they live underground (bear with me, I am channelling DnD tropes here), even though based on our current biology, underground creatures are lighter skinned since they do not need protection from sunlight.
Having said the above, darker skinned sun-elves would garner more respect for Forbidden Lands.
I am still unsure whether the core races of Forbidden Lands will all share a common ancestor especially, with regards to the orcs and large ogres?
And if they share a common ancestor, then it would seem logical to allow both orcs and ogres as Player races during character creation.
