There was only one act left, and that was to seal the chambers. Eligor took a final look at the familiar, once-inviting rooms, picked up the large volume, and closed the door behind him. He produced the red seal that Sargatanas had given him and, with a wave of his hand, floated it directly over the door’s lintel. When the seal was in place he uttered a command and watched the complex glyph replicate itself dozens of times until a hundred identical copies had slowly outlined the door frame. He then extended his hand to touch the door and a hundred swift glyph-arrows converged to prevent him from making contact; had he persisted he would have been destroyed. He pulled his stinging hand back. It was done.
