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.

Millennia ago, aberrations from Xoriat, the Realm of Madness, were driven from Eberron. The Gatekeeper druids–mostly orcs–placed powerful dimensional seals throughout Khorvaire to prevent the creatures of Xoriat from returning. To repair a breach in one of the seals at a settlement called Tjorda, a Sealguard Complex was built. An immortal guardian ws tasked with attending to the repaired crack in the seal. Thousands of years later, the Gatekeeper druids rediscovered the sealed complex. Even without knowing its precise history, they ascertained its sacred nature and have guarded it from then on. Being sealed in to protect the site and commune with the inner guardian is considered a great honor. Much of this history has long-since been forgotten. But 10 years prior to the adventure’s start, Vilda Karrte–a relic hunter with her own agenda–tracks a Xoriat artifact called the Spiral Well to the complex. Turned away by the Gatekeeper, she forces her way inside, grievously injuring them. Having discovered Vilda’s journals, Provost Nigel Faurious, through the Clifftop Adventurers’ Guild Handler Lhara, tasks the adventurers with recovering the Spiral Well.
