The Wood Elves made an agreement to give themselves up to the Demons. They would give advice on many things including strategy that they had taught to humans and animal-folk. What the Wood elves did not know at the time is that their capital city was already under siege by the combined Demon, Orc & Hobgoblin forces. What came next was the curse that exists even today. Giving themselves up to the demon forces, and more specifically the leader of the Demon Forces they opened themselves up to be cursed. Giving this control to the enemy allowed them to be cursed with near immortality as well as becoming, in part what they feared or hated most. In a few cases they became what they loved most which can sometimes be worse. The Dark Elves according to human and animal-folk are immortal as they cannot die. Even if they fall in battle their bodies will regenerate. It is painful and may take days for this to occur. What the Dark Elves believe is that once their Demon nemesis is destroyed their curse will be lifted. Rendered in Daz Studio 4.14 with 3Delight. No post work done.
