The Herald of Thanatos is a massive mechanical construct that roams the lands, in its wake the dead rise from their graves and follow the machine as a legion of undead warriors.
It's really interesting to see this wonderful illustrastion. It gives us alot of room to speculate to what the Age of the Wolf was really about. Based on this illustration alone, I'm getting associations with the Iron Kingdoms, perhaps with a hint of post apocalypse? The challenge with such a setting would probably be how to preserve the Arnesonian touch to the setting. I hope to reveal more news on this topic in the coming months!
