“Part of the path is independent research, Lady Abigail,” said Teacher, smiling. “The other part, the greater part, is the silence … is the care. You are not alone in the facility. In its heart lies the Sleeper, and how long that creature has lain there I do not know; but I do know that they are your greatest threat, for although they lie in sleep … in that sleep, they walk.”

Here he trailed off. He stared into the middle distance, still grasping his cup of tea, as though seeing visions the assembled scions and cavaliers were not privy to. The pause stumbled execrably, fell down the stairs, and lay in a tangle at the bottom in full view of all listeners, who had to watch it bleed out in embarrassment. One of the grotesquely young pair of the Fourth actually tried to fill it in, and bleated: “There’s a—monster in a research laboratory? And we’ve got to—fight it?”

“No, no!” said Teacher impatiently. “Lord Over the River have mercy! The Sleeper cannot die. I doubt they can be wounded; they certainly cannot be killed. The greatest advantage we have is that the Sleeper sleeps deeply! The second threat to your work is if the Sleeper wakes—it has never happened, though I know the Sleeper yearns to escape its incognizant state and pick up where they left off—for if they wake, none of us will live. If the Sleeper meets you on their unconscious peregrinations, your weapon should be stealth; if through unholy means you wake them, there will be no other weapons left. We are reliant on a communal soundlessness. Travel in groups; tread softly; go where I durst not go: because I love my life, and I love noise, also.”
