Sauron The Deceiver

Sauron in the ethereal guise of his elven form, which he used to learn how to smith and create the rings of power along with the one ring. In The Hobbit he's briefly mentioned as The Necromancer.

This was my entry for The Hobbit contest, it didn't make it into the semi-finals but I'm not sad about it, it was nice just to make a piece and have it seen by some of the great concept artists who worked on The Lord of the Rings series.
