Slowly he regained consciousness, but it was a long time before he could marshal his faculties to even a slight appreciation of the catastrophe that had overwhelmed him. Then his first thought was of Nadara. He crawled to what had once been the entrance of his cave. He had not as yet linked the darkness to its real cause--he thought it night. It had been night when he closed his eyes. How could he guess that that had been three nights before, or all the cruel blows that fate had struck him since he slept! At the opening from the cave he met his first surprise and setback--the way was blocked! What was the meaning of it? He tugged and pushed weakly upon the mass that barred him from escape. Who had imprisoned him? He recalled the vivid dream in which he had seen Nadara stolen away by Thurg. The recollection sent him frantically at the pile of shattered rock and loose debris which choked the doorway. To his chagrin he found himself too weak to direct any long sustained effort against the obstacle. It occurred to him that he must have been injured. Whoever imprisoned him must first have beaten him. He felt of his head. Yes, there was a great gash, but his touch told him that it was not a new one. How long, then, had he been imprisoned? As he sat pondering this thing he became aware of the gnawing of hunger and the craving of thirst within his slowly awakening body. The sensations were almost painful. So much so that they forced him to a realization of the fact that he must have been without food or water for a considerable time. Again he assailed the mass that held him prisoner, and as he burrowed slowly into it the truth dawned upon him. He recalled the rumblings of the Great Nagoola that had frightened Nadara the night of the council. A terrific quake had done this thing. Thandar shuddered as he thought of Nadara. Was she, too, imprisoned in her cave, or had the worst happened her? Frantically, now, he tore at the close-packed rubble. But he soon discovered that not in ill-directed haste lay his means of escape. Slowly and carefully, piece by piece he must remove the broken rock until he had tunnelled through to the outer world. Reason told him that he was not deeply buried, for the fact that he lived and could breathe was sufficient proof that fresh air was finding its way through the debris, which it could not have done did the stuff lie before the cave in any considerable thickness. Weak as he was he could work but slowly, so that it was several hours later before he caught the first glimpse of daylight beyond the obstacle. After that he progressed more rapidly, and presently he crawled through a small opening to view the wreckage of the shattered cliff.
