The forest thinned before him. There was a flicker of swift motion far ahead. Stuart froze, his grip tightening on the cudgel, his eyes searching. Between the columnar trees, bright amid the purple shadows, a glitter of sparkling nebulae swept. A web of light, Stuart thought--so dazzling his eyes ached as he stared at the--the thing. Bodiless, intangible, the shifting net of stars poised, high above his head. Hundreds of twinkling, glittering pinpoints flickered there, so swiftly it seemed as though an arabesque spider-web of light weaved in the still, dark air--web of the Norns! Each flickering star-fleck--watched. Each was an eye. And as the thing poised, a horrible, half-human hesitancy in its stillness, a deep, humming note sounded, from its starry heart. Star-points shook and quivered to the sound. Again it came--deeper, more menacing. Questioning! Was this one of the--Watchers? Was this one of them? * * * * * Abruptly its hesitancy vanished; it swept down upon Stuart. Instinctively he swung his cudgel in a smashing blow that sent him reeling forward--for there was no resistance. The star-creature was as intangible as air. And yet it was not. The dazzling web of light enfolded him like a blazing cloak. Instantly a cold, trembling horror crawled along his skin. Bodiless the thing might be--but it was dangerous, infinitely so! Pressure, shifting, quicksand pressure, was all about him. That stealthy cold crept into his flesh and bones, frigid icicles jabbing into his brain. Gasping with shock, Stuart struck out. He had dropped the club. Now he stooped and groped for it, but he could see nothing except a glittering veil of diamonds that raced like a mad torrent everywhere. The humming rose again--ominously triumphant. Cursing, Stuart staggered forward. The star-cloak stayed. He tried to grip it somewhere, to wrench it free, but he could not. The thousands of tiny eyes raced past him, glittering with alien ecstasy, shining brighter and ever brighter as they fed. He felt the life being sucked out of him.... Deeper stabbed the gelid cold ... louder roared that throbbing tone in his ears. He heard his voice gasping furious, hopeless oaths. His eyes ached with the strain of staring at that blinding glitter. Then-- _The heart of the Watcher. Crush the heart!_ The words crashed like deep thunder in his brain. Had someone spoken them--? No ... for, with the command, had come a message as well. As though a thought had spoken within his mind, a telepathic warning from--where? His eyes strained at the dazzle. Now he saw that there was a brighter core that did not shift and change when the rest of the star-cloud wove its dreadful net. A spot of light that-- He reached out ... the nucleus darted away ... he lurched forward, on legs half-frozen, and felt a stone turn under his foot. As he crashed down, his hand closed and tightened on something warm and living that pulsed frantically against his palm.
