Zombra
An iron rock in the river of blood and evil
Why is Mordor brown and brightly lit? The name means "Black Land" or "Land of Darkness" in the lore, and many of the warped creatures of Mordor couldn't bear the sun.
As a child, long before the movies, I read Lord of the Rings and this is exactly how I imagined Mordor, except even more vague, shadowed, and mysterious. I may have seen an illustration somewhere as well.
For whatever it's worth, they talk about this some in the interviews. Shadow is set decades before Lord of the Rings, when Sauron's darkity evil hasn't consumed the land yet. Sounds like it doesn't hold together to me if the freaking name means darkity dark ... but in case it makes you feel better, or worse, this was a conscious decision by the devs and they have a rationale for it.
