Stormwall shields. Not many are left, these days—most were destroyed in a series of devastating civil wars that plagued and ultimately fractured the Sovereignty of Helicon-Helix, the first multiverse-spanning empire that dominated hundreds of worlds, spanning dozens of realms. Initially used by the Sentries, an elite military force sworn to protect the Empire to their last breath, Stormwall shields are now scattered through the multiverse—many are hidden under torched, ancient ruins of broken worlds, some are sold at incredible prices at heavily guarded antique shops, and only a handful are in possession of those rich—or brave enough to acquire them.
