So the Lich King recognizes Jin-Woo as "(Shadow) Monarch". I'm betting that the "Shadow Monarch" ability is given by the dungeon system, and Jin-Woo is supposed to be a "boss" from the dungeons, or at least has the power from it. That's why the Orc leader didn't see him as a human. His abilities make him one of the dungeon monsters, and probably one of the more powerful ones at that. Probably has the power of one of their gods or something. I can't wait to find out~~
