The caravan halted on an oval area covered with thick short grass, and Baojian immediately called all the personnel of the caravan about him. "This is Golsse, an Old Chasch city. Do not leave the immediate area, or you may be subject to Old Chasch tricks. These can be mere mischiefs' such as trapping you in a maze or dosing you with an essence that will cause you to exude a frightful odor for weeks. But if they become excited, or feel particularly humorous, the tricks may be cruel or fatal. On one occasion they stupefied one of my drivers with essence, grafted new features on his face and a great gray beard as well.
Remember, then: do not under any circumstances stray from this oval, even though the Chasch may tease or tempt you. They are an old and decayed race; they are without pity and think only of their odors and essences, and their fanciful jokes. So be warned: keep to the oval, do not wander off in the gardens, no matter what the beguilement, and if you value your life and sanity, do not enter the Old Chasch domes."
He said no more.
Goods were loaded upon the low Chasch motor-drays, operated by a few dispirited Chaschmen: smaller and perhaps not so evolved as the Blue Chaschmen Reith had seen before. They were slight and stooped, with gray wrinkled faces, bulging foreheads, mouths puckered into little buds above nonexistent chins. Like the Blue Chaschmen they wore a false scalp which butted over their eyes and rose to a point. Their demeanor was furtive and hurried, they spoke to none of the caravan personnel, and had eyes only for their work. Four Old Chasch presently appeared. They walked directly below the barrack car; Reith saw them close at hand and was reminded of large silverfish grotesquely endowed with semi-human legs and arms. Their skin was like ivory satin, almost imperceptibly scaled; they seemed fragile, almost desiccated; they had eyes like small silver pellets, independently swiveling and in constant motion. Reith watched them with great interest; they felt his gaze and paused to look up to where he sat. They nodded and gave him affable gestures, to which Reith replied in kind. For a moment longer they inspected him with their bright silver eyes, and then passed on.
Baojian wasted no time at Golsse. As soon as he had reloaded his drays with cases of drugs and tinctures, bales of lacy cloth, dried fruit in cakes and packs, he marshaled the wagons and set off once more to the north, preferring to pass the night on the open steppe rather than risk the caprices of the Old Chasch.
The steppe was empty grassland, flat as a table. Standing on the barrack-wagon Reith could see twenty miles through his scope, and so spied a large band of Green Chasch even before the scouts. He notified Baojian, who immediately ordered the caravan into a defensive ring with the guns commanding the entire surrounding area. The Green Chasch loped up on their massive beasts, holding yellow and black flags afloat on their lances, signifying truculence and bellicosity. "They have just come down from the north," Traz told Reith. "This is the meaning of the flags. They gorge on fluke-fish and angbut; their blood becomes rich and thick, which makes them irritable. When they fly yellow and black even the Emblems retire rather than face them in battle."
Yellow and black flags regardless, the Green warriors did not molest the caravan but halted a mile distant. Reith studied them through his scope, to see creatures vastly different from the Old Chasch. These were seven and eight feet tall, massive and thick-limbed, their scales clearly defined and of a glistening metallic green. Their faces were small, brooding, wickedly ugly under the massive jut of their scalps. They wore rude leather aprons and shoulder harness, in which hung swords, battle-picks and catapults similar to those of the Emblems. Troublesome creatures to encounter in close combat, thought Reith. They sat on their beasts studying the caravan for a full five minutes, then swung away and bounded off to the east.
The caravan re-formed itself and continued along the track. Traz was puzzled by the diffidence of the Green Chasch. "When they carry yellow and black, they are insensate. Perhaps they prepare an ambush from behind a forest."
Baojian suspected a similar stratagem and kept his scouts far forward for the next few days. At night there were no special precautions taken, inasmuch as the Green Chasch became torpid in the dark and huddled in groaning grunting masses until daybreak.
Pera lay ahead: the caravan terminus. Reith's transcom specified a vector of sixty miles west to the mate transcom. He made inquiry of the caravan-master, who informed him that the Blue Chasch city Dadiche was situated at this location. "Avoid them; a wicked lot they are, subtle as the Old Chasch, savage as the Greens."
"They have no commerce with men?"
"There is considerable trade; in fact, Pera is a depot for trade with the Blue Chasch, which is carried on by a caste of draymen operating out of Pera; only these draymen gain access to Dadiche. Of all the Chasch I find the Blues most detestable. The Old Chasch are not a friendly folk, but they are malicious, rather than harsh. Sometimes of course, the effect is the same, just as the storm"-he pointed toward the west where great masses of black cloud filled the sky-"will wet us no less than submersion in the ocean."
"You will turn directly about at Pera and return to Coad on the Dwan Zher?"
"Within three days."
"In all likelihood the Princess Ylin-Ylan will return with you and take ship for Cath."
"All very well; can she pay?"
"Certainly."
"Then there is no difficulty. What of you? Do you wish to go to Cath likewise?"
"No. I'll probably remain at Pera."
Baojian, with a darting glint of a glance for Reith, gave his head a wry shake.
"The Golden Yao of Cath are estimable folk. But then, nothing of Tschai is predictable except trouble. The Green Chasch are dogging us. A miracle that they have not attacked. I begin to hope that we may reach Pera without incident."
Baojian was to be denied. With Pera already in view-a city of ruined halls and toppled monuments surrounding a central citadel, much like those others they had passed-the Green Chasch bounded in from the east. Coincidentally the storm broke. Lightning crashed down upon the steppe; to the south black brooms of rain swept down upon the land.
Baojian decided that Pera offered no refuge and ordered the caravan into its defensive circle. Barely soon enough: this time the Green Chasch showed neither indecision nor diffidence. Bent low on their great beasts, they came charging forward, intent only on penetrating the ring of wagons.
The caravan guns gave their curious gurgling belch, barely heard through the thunder, and the rain made efficient weapon handling difficult. The Green Chasch, coordinated perhaps telepathically, bounded forward; some were struck by the sand blast and killed; some were crushed under their toppling beasts. For a space there was sheer confusion, then new ranks sprang over the thrashing bodies. Again the gunners fired frantically through the rain, with the lightning and thunder providing a mind jarring accompaniment to the battle.
The Green Chasch fell faster than they could advance, and changed their tactics.
