The Darsilv

With their longer life span and sensitivity to the forces of magic, elves are also sensitive to the shadows of Kram and other forces of darkness. At some point in their lifetime, every elf will face the Nages, or shadows of Kram. Most elves can withstand the temptations of the Nages, but a few will succumb, and devote their lives to evil. They will become Darsilv, or Black Elves. The ability to resist the Nages seems to follow lineage, and so elves whose ancestors succumbed are usually more likely to succumb themselves. Elves raised among the Darsilv often don't even try to resist the call of the Nages. Physically, there is very little to distinguish the Darsilv from other silv, however, they do often have a more pale complexion due to the time spent indoors, underground and being active under the cover of night.
