Guyal said, "My lord Curator, I must speak words with you."

The old man halted, peered. "Eh? What now? At the end of a long day's effort? No, no, you are out of order; regulation must be observed.

Attend my audiarium at the fourth circuit tomorrow morning; then we shall hear you. So go now, go."

Guyal fell back nonplussed. Shierl fell on her knees. "Sir Curator, we beg you for help; we have no place to go."

Kerlin the Curator looked at her blankly. "No place to go! What folly you utter! Go to your domicile, or to the Pubescentarium, or to the Temple, or to the Outward Inn. For-sooth, Thorsingol is free with lodging; the Museum is no casual tavern."

"My lord," cried Guyal desperately, "will you hear me? We speak from emergency."

"Say on then."

"Some malignancy has bewitched your brain. Will you credit this?"

"Ah, indeed?" ruminated the Curator.

"There is no Thorsingol. There is naught but dark waste. Your city is an eon gone."

The Curator smiled benevolently. "Ah, sad ... A sad case. So it is with these younger minds. The frantic drive of life is the Prime Unhinger." He shook his head. "My duty is clear. Tired bones, you must wait your well-deserved rest. Fatigue—begone; duty and simple humanity make demands; here is madness to be countered and cleared. And in any event the Nocturnal Key-keeper is not here to relieve me of my tedium." He beckoned. "Come."

Hesitantly Guyal and Shierl followed him. He opened one of his doors, passed through muttering and expostulating with doubt and watchfulness, Guyal and Shierl came after.

The room was cubical, floored with dull black stuff, walled with myriad golden knobs on all sides. A hooded chair occupied the center of the room, and beside it was a chest-high lectern whose face displayed a number of toggles and knurled wheels.

'This is the Curator's own Chair of Knowledge," explained Kerlin. "As such it will, upon proper adjustment, impost the Pattern of Hynomeneural Clarity. So—I demand the correct sometsyndic arrangement—" he manipulated the manuals "—and now, if you will compose yourself, I will repair your hallucination. It is beyond my normal call of duty, but I am humane and would not be spoken of as mean or unwilling."

Guyal inquired anxiously, "Lord Curator, this Chair of Clarity, how will it affect me?"

Kerlin the Curator said grandly, "The fibers of your brain are twisted, snarled, frayed, and so make contact with unintentional areas. By the marvelous craft of our modern cerebrologists, this hood will compose your synapses with the correct readings from the library—those of normality, you must understand—and so repair the skein, and make you once more a whole man."

"Once I sit in the chair," Guyal inquired, "what will you do?"

"Merely close this contact, engage this arm, throw in this toggle—then you daze. In thirty seconds, this bulb glows, signaling the success and completion of the treatment. Then I reverse the manipulation, and you arise a creature of renewed sanity."
