The green dwarf was signalling us for caution. He pointed through a break in a grove of fifty-foot cedar mosses⁠—we were skirting the glassy road! Scanning it we found no trace of Lugur and wondered whether he too had seen the worm and had fled. Quickly we passed on; drew away from the coria path. The mosses began to thin; less and less they grew, giving way to low clumps that barely offered us shelter. Unexpectedly another screen of fern moss stretched before us. Slowly Rador made his way through it and stood hesitating.
