The First Book of Lankhmar

commanded an act, when curiosity and fascination tipped the scale of caution, when the lure of a vision and an adventure became so great and deep-hooking that he must respond to it or have his inmost self-respect eaten away.
           Besides, he knew from long experience that the only way to extricate Fafhrd from the predicaments into which he got himself was to go fetch the perfumed and be-sworded lout!
           So the Mouser sprang up lightly, clipped to his underbelt his sealskin-cased weapons, hung beside them in loops a short length of knotted line with a slip-noose tied in one end, made sure that the sloop's hatches were securely covered and even that the galley fire was tightly boxed, rattled off a short scornful prayer to the gods of Lankhmar, and lowered himself off the bowsprit and down into the green hole.
           The hole was chilly, and it smelled of fish, smoke, and Fafhrd's pomade. The Mouser's main concern as soon as he got in it, he discovered to his surprise, was not to touch its glassy sides. He had the feeling that if he so much as lightly brushed it, the water's miraculous "skin" would rupture, and he would be engulfed — rather as an oiled needle floating on a bowl of water in its tiny hammock of "water skin" is engulfed and sinks when one pinks it. He descended rapidly knot by knot, supporting himself by his hands, barely touching his toes to the rope below, praying there would be no sway and that he would be able to check it if it started. It occurred to him he should have told Fafhrd to guy the rope at the bottom if he possibly could and above all have warned him not to shout up the tube while the Mouser descended — the thought of being squeezed by those dread water-rings was almost too much to bear. Too late now — any word now would only too surely bring a bellow from the Northerner in reply.
           First fears having been thus inspected, though by no means banished, the Mouser began to take some note of his surroundings. The luminous green world was not just one emerald blank as it had seemed at first. There was life in it, though not in the greatest abundance: thin strands of scalloped maroon seaweed, near-invisible jellyfish trailing their opalescent fringes, tiny dark skates hovering like bats, small silvery backboned fish gliding and darting — some of them, a blue-and-yellow-ringed and black-spotted school, even contesting lazily over the Black Treasurer's morning garbage, which the Mouser recognized by a large pallid beef bone Fafhrd had gnawed briefly before tossing overside.
           Looking up, he was hard put not to gasp in horror. The hull of the sloop, pressing down darkly, though pearled with bubbles, looked seven times higher above him than the distance he had descended by his count of the knots. Looking straight up the tube, however, he saw that the circle of deep blue sky had not shrunk correspondingly, while the bowsprit bisecting it was still reassuringly thick. The curve of the tube had shrunk the sloop as it had the shark. The illusion was most weird and foreboding, nonetheless.
           And now as the Mouser continued his swift descent, the circle overhead did grow smaller and more deeply blue, becoming a cobalt platter, a peacock saucer, and finally no more than a strange ultramarine coin that was the converging point of the tube and rope and in which the Mouser thought he saw a star flash. The Gray One puffed a few rapid kisses toward it, thinking how like they were to a drowning man's last bubbles. The light dimmed. The colors around him faded, the maroon seaweed turned gray, the fish lost their yellow rings, and the Mouser's own hands became blue as those of a corpse. And now he began to make out dimly the sea bottom, at the same extravagant distance below as the sloop was above, though immediately under him the bottom was oddly veiled or blanketed and only far off could he make out rocks and ridged stretches of sand.
           His arms and shoulders ached. His palms burned. A monstrously fat grouper swam up to the tube and followed him down it, circling. The Mouser glared at it menacingly, and it turned on its side and opened an impossibly large moon crescent of mouth. The Mouser saw the razor teeth and realized it was the shark he'd seen or another like it, tinied by the lens of the tube. The teeth clashed, some of them inside the tube, only inches from his side. The water's "skin" did not rupture disastrously, although
