Delphi Complete Works of H. P. Lovecraft(419)
In the year 1545, as he reckoned it, Zamacona began what may well be accepted as his final series of attempts to leave K’n-yan. His fresh opportunity came from an unexpected source — a female of his affection-group who conceived for him a curious individual infatuation based on some hereditary memory of the days of monogamous wedlock in Tsath. Over this female — a noblewoman of moderate beauty and of at least average intelligence named T’la-yub — Zamacona acquired the most extraordinary influence; finally inducing her to help him in an escape, under the promise that he would let her accompany him. Chance proved a great factor in the course of events, for T’la-yub came of a primordial family of gate-lords who had retained oral traditions of at least one passage to the outer world which the mass of people had forgotten even at the time of the great closing; a passage to a mound on the level plains of earth which had, in consequence, never been sealed up or guarded. She explained that the primordial gate-lords were not guards or sentries, but merely ceremonial and economic proprietors, half-feudal and baronial in status, of an era preceding the severance of surface-relations. Her own family had been so reduced at the time of the closing that their gate had been wholly overlooked; and they had ever afterward preserved the secret of its existence as a sort of hereditary secret — a source of pride, and of a sense of reserve power, to offset the feeling of vanished wealth and influence which so constantly irritated them.
Zamacona, now working feverishly to get his manuscript into final form in case anything should happen to him, decided to take with him on his outward journey only five beast-loads of unalloyed gold in the form of the small ingots used for minor decorations — enough, he calculated, to make him a personage of unlimited power in his own world. He had become somewhat hardened to the sight of the monstrous gyaa-yothn during his four years of residence in Tsath, hence did not shrink from using the creatures; yet he resolved to kill and bury them, and cache the gold, as soon as he reached the outer world, since he knew that even a glimpse of one of the things would drive any ordinary Indian mad. Later he could arrange for a suitable expedition to transport the treasure to Mexico. T’la-yub he would perhaps allow to share his fortunes, for she was by no means unattractive; though possibly he would arrange for her sojourn amongst the plains Indians, since he was not overanxious to preserve links with the manner of life in Tsath. For a wife, of course, he would choose a lady of Spain — or at worst, an Indian princess of normal outer-world descent and a regular and approved past. But for the present T’la-yub must be used as a guide. The manuscript he would carry on his own person, encased in a book-cylinder of the sacred and magnetic Tulu-metal.
The expedition itself is described in the addendum to Zamacona’s manuscript, written later, and in a hand shewing signs of nervous strain. It set out amidst the most careful precautions, choosing a rest-period and proceeding as far as possible along the faintly lighted passages beneath the city. Zamacona and T’la-yub, disguised in slaves’ garments, bearing provision-knapsacks, and leading the five laden beasts on foot, were readily taken for commonplace workers; and they clung as long as possible to the subterranean way — using a long and little-frequented branch which had formerly conducted the mechanical transports to the now ruined suburb of L’thaa. Amidst the ruins of L’thaa they came to the surface, thereafter passing as rapidly as possible over the deserted, blue-litten plain of Nith toward the Grh-yan range of low hills. There, amidst the tangled underbrush, T’la-yub found the long disused and half-fabulous entrance to the forgotten tunnel; a thing she had seen but once before — aeons in the past, when her father had taken her thither to shew her this monument to their family pride. It was hard work getting the laden gyaa-yothn to scrape through the obstructing vines and briers, and one of them displayed a rebelliousness destined to bear dire consequences — bolting away from the party and loping back toward Tsath on its detestable pads, golden burden and all.
It was nightmare work burrowing by the light of blue-ray torches upward, downward, forward, and upward again through a dank, choked tunnel that no foot had trodden since ages before the sinking of Atlantis; and at one point T’la-yub had to practice the fearsome art of dematerialisation on herself, Zamacona, and the laden beasts in order to pass a point wholly clogged by shifting earth-strata. It was a terrible experience for Zamacona; for although he had often witnessed dematerialisation in others, and even practiced it himself to the extent of dream-projection, he had never been fully subjected to it before. But T’la-yub was skilled in the arts of K’n-yan, and accomplished the double metamorphosis in perfect safety.
