Void Seer Mordikaar - Skorne Warlock
"The void seer is a walking contradiction whose very existence throws doubt on the most deeply held skorne beliefs. Though terrifying, his presence is also a reminder to those following Supreme Archdomina Makeda that in her army nothing is impossible. Among her chosen warlords Mordikaar has defied the ultimate power of death."
Last of the new warlocks from Hordes: Metamorphosis. A lot of weird choices went into this dude, but I think it all made for a highly unique character. Definitely a favorite of mine.
