The Glaive Seal is an artifact used in Hub 5: Necropolis in Hexen. It is one of the three items that open one of the doors blocking the path to Dark Crucible, and it is obtained after defeating Zedek in his tomb. It looks like a smaller version of the Quietus. In Deathkings of the Dark Citadel, the Glaive Seal reappears in the Nave.
