The cog approached the coast of Kachan, where the captain hoped to ride north-flowing currents up into the Parapan.
One morning, coming on deck, Reith found a remarkable island standing off the starboard beam: a place of no great extent, less than a quarter-mile in diameter, surrounded at the water's edge by a wall of black glass a hundred feet high. Beyond rose a dozen massive buildings of various heights and graceless proportion.
Anacho the Dirdirman came to stand beside him, narrow shoulders hunched, long face dour. "There you see the stronghold of an evil race: the Wankh."
"'Evil'? Because they are at war with the Dirdir?"
"Because they will not end the war. What benefit to either Dirdir or Wankh is such a confrontation? The Dirdir offer disengagement; the Wankh refuse. A harsh inscrutable people!"
"Naturally, I know nothing of the issues," said Reith. "Why the wall around the island?"
"To daunt the Pnume, who infest Tschai like rats. The Wankh are not a companionable folk. In fact-look down yonder below the surface."
Reith, peering into the water, saw gliding beside the ship at a depth of ten or fifteen feet a dark man-like shape, with a metal structure fixed across its mid-body, moving without motion of its own. The figure twisted, slanted away and vanished into the murk.
"An amphibious race, the Wankh, with electric jets for their underwater sport."
Reith once more raised the scanscope. The Wankh towers, like the walls, were black glass. Round windows were discs blacker than black; balconies of frail twisted crystal became walkways to far structures. Reith spied movement: a pair of Wankh? Looking more closely he saw the creatures to be men-Wankhmen, beyond all doubt, with flour-white skins and black pelts close to somewhat flat scalps.
Their faces seemed smooth, with still, saturnine features; they wore what appeared to be one-piece black garments, with wide black leather belts, on which hung small implements, tools, instruments. As they moved into the building, they looked out at the Vargaz and for an instant Reith saw full into their faces. He jerked the scanscope from his eyes.
Anacho eyed him askance. "What is the trouble?"
"I saw two Wankhmen ... Even you, weird mutated freak that you are, seem ordinary by comparison."
Anacho gave a sardonic chuckle. "They are in fact not dissimilar to the typical sub-man."
Reith made no argument; in the first place he could not define the exact quality he had seen behind the still white faces. He looked again, but the Wankhmen had disappeared. Dordolio had come out on deck and now stared in fascination at the scanscope. "What instrument is that?"
"An electronic optical device," said Reith without emphasis.
"I've never seen its like." He looked at Anacho. "Is it a Dirdir machine?"
Anacho made a quizzical dissent. "I think not."
Dordolio gave Reith a puzzled glance. "Is it Chasch or Wankh?" He veered at the engraved escutcheon. "What writing is this?"
Anacho shrugged. "Nothing I can read."
Dordolio asked Reith: "Can you read it?"
"Yes, I believe so." Impelled by a sudden mischievous urge, Reith read:
"Federal Space Agency Tool and Instrument Division Mark XI Photomultiplying Binocular Telescope
1x-1000x Nonprojective, inoperable in total darkness. BAF-1303-K-29023 Use Type D5 energy slug only. In poor light, engage color compensator switch. Do not look at sun or high-intensity illumination; if automatic light-gate fails, damage to the eyes may result."
Dordolio stared. "What language is that?"
"One of the many human dialects," said Reith.
"But from what region? Men everywhere on Tschai, to my understanding, speak the same language."
"Rather than embarrass you both," said Reith. "I prefer to say nothing. Continue to think of me as an amnesiac."
"Do you take us for fools?" growled Dordolio. "Are we children to have our questions answered with flippant evasions?"
"Sometimes," said Anacho, speaking into the air, "it is the part of wisdom to maintain a myth. Too much knowledge can become a burden."
Dordolio gnawed at his mustache. From the corner of his eye he glanced at the scanscope, then swung abruptly away.
Ahead three more islands had appeared, rising sharply from the sea, each with its wall and core of eccentric black buildings. A shadow lay on the horizon beyond: the mainland of Kachan.
During the afternoon the shadow took on density and detail, to become a hulk of mountains rising from the sea. The Vargaz coasted north, almost in the shadow of the mountains, with black dip-winged kites swooping around the masts, emitting mournful hoots and clashing their mandibles. Late in the afternoon the mountains fell away to reveal a landlocked bay. A nondescript town occupied the south shore; from a promontory to the north rose a Wankh fortress, like a growth of undisciplined black crystals. A spaceport occupied the flat land to the east, where a number of spaceships of various styles and sizes were visible.
Through the scanscope, Reith studied the landscape and the mountainside sloping down to the spacefield from the east. Interesting, mused Reith, interesting indeed.
The captain, coming past, identified the port as Ao Hidis, one of the important Wankh centers. "I had no intent of faring south so far, but since we're here, I'll try to sell my leathers and the Grenie woods; then I'll take on Wankh chemicals for Cath. A word of warning for those of you who intend to roister ashore. There are two towns here: Ao Hidis proper, which is Man-town, and an unpronounceable sound which is Wankh-town. In Man-town are several kinds of people, including Lokhars, but mainly Blacks and Purples. They do not mingle; they recognize their own kind only. In the streets you may walk without fear, you may buy at any shop or booth with an open front. Do not enter any closed shop or tavern, either Black or Purple; you'll likely not come out.
There are no public brothels. If you buy from a Black booth, do not stop at a Purple booth with your goods; you will be resented and perhaps insulted, or, in certain cases, attacked. The opposite holds true. As for Wankh-town, there is nothing to do except stare at the Wankh, to which you are welcome, for they do not seem to object. All considered, a dull port, with little amusement ashore."
The Vargaz eased alongside a wharf flying a small purple pennon. "I patronized Purple on my last visit," the captain told Reith who had come up to the quarterdeck. "They gave good service at a fair price; I see no reason to change."
The Vargaz was moored by Purple longshoremen: roundfaced, roundheaded men with a plum-colored cast to their complexion. From the neighboring Black dock Blacks looked on with aloof hostility. These were physiognomically similar to the Purples, but with gray skins oddly mottled with black.
"No one knows the cause," the Captain said, in regard to the color disparity.
"The same mother may produce one Purple child and one Black. Some blame diet; others drugs; others hold that disease attacks a color-gland in the mother's egg. But Black and Purple they are born; and each calls the other pariah. When Black and Purple breed, the union is sterile, or so it is said. The notion horrifies each race; they would as soon couple with nighthounds."
"What of the Dirdirman?" asked Reith. "Is he likely to be molested?"
"Bah. The Wankh take no notice of such trivia. The Blue Chasch are known for sadistic malice. Dirdir stringencies are unpredictable. But in my experience the Wankh are the most indifferent and remote people of Tschai, and seldom trouble with men. Perhaps they do their evil in secret like Pnume; no one knows. The Wankhmen are a different sort, cold as ghouls, and it is not wise to cross them.
Well then, we are docked. Are you going ashore? Remember my warnings; Ao Hidis is a harsh city. Ignore both Black and Purple; talk to no one; interfere with nothing. Last visit I lost a seaman who bought a shawl at a Black shop, then drank wine at a Purple booth. He staggered aboard the ship with foam coming from his nose."
