"Why not flip that?" he asked. "Heads, we go that way—" he indicated the direction in which they were facing—"tails, we do a rightabout-face."
There was an answering grin on Thorvald's lips. "As good a guide as any we're likely to find here. We'll do it." He pulled away the twist of cloth and with a swift snap, reminiscent of that used by the Warlockian witch to empty the bowl of sticks, he tossed the disk into the air.
It spun, whirled, but—to their open-jawed amazement—it did not fall to the sand. Instead it spun until it looked like a small globe instead of a disk. And it lost its dead white for a glow of green. When that glow became dazzling for Terran eyes the miniature sun swung out, not in orbit but in straight line of flight, heading to their right.
With a muffled cry, Thorvald started in pursuit, Shann running beside him. They were in a tunnel of the fog now, and the pace set by the spinning coin was swift. The Terrans continued to follow it at the best pace they could summon, having no idea of where they were headed, but each with the hope that they finally did have a guide to lead them through this place of confusion and into a sane world where they could face on more equal terms those who had sent them there.
14. ESCAPE
"Something ahead!" Thorvald did not slacken the pace set by the brilliant spot of green they trailed. Both of the Terrans feared to fall behind, to lose touch with that guide. Their belief that somehow the traveling disk would bring them to the end of the mist and its attendant illusions had grown firmer with every foot of ground they traversed.
A dark, fixed point, now partly veiled by mist, lay beyond, and it was toward that looming half-shadow that the spinning disk hurtled. Now the mist curled away to display its bulk—larger, blacker and four or five times Thorvald's height. Both men stopped short, for the disk no longer played pathfinder. It still whirled on its axis in the air, faster and faster, until it appeared to be throwing off sparks, but the sparks faded against a monolith of dark rock unlike the native stone they had seen elsewhere. For it was neither red nor warmly brown, but a dull, dead black. It could have been a huge stone slab, trimmed, smoothed, set up on end as a monument or marker, except that only infinite labor could have accomplished such a task, and there was no valid reason for such toil as far as the Terrans could perceive.
"This is it." Thorvald moved closer.
