The battles of the Blood War have raged for longer than mortals have known life, the conflict's savagery and hatred fueling the dreams, desires and obsessions of the multiverse. One way or another, the war spills through all the layers of existence, and little escapes its influence. Some clashes have consequences that shake the Lower Planes. Others are far less meaningful - they're fought solely for the sake of violence and killing. "The Field of Nettles" is set in the aftermath of an especially pointless battle. The adventure rips the player characters from their comfortable lives and thrusts them into the Blood War full force. The goal is to cross one of the more infamous battlefields, seeing the scope and the power of the fighting - and hopefully coming away with a greater understanding of just how big the Blood War is. The adventure is designed for a party of 4-6 PCs of 5th-8th level. The characters don't get to save the multiverse, nor do they find the key to unlock the dark of any great secrets. But they might come to realize their importance (or lack of it) in the scheme of things. On the fickle borders of the planes, that can be worth almost as much.
