Did you buy your seals from lunatic fringe? I believe all the seals are blue, but when they arrive at his shop, they slowly turn black, to match the evil in his soul, like the Chuck Norris Sith Lord that he is. He is probably sitting on a beach in Florida, soaking up the sun and drinking some froo froo drink made from the tears of children. Damn, I miss that guy.
