| Synopsis | The Kull are a peaceful people who have discovered random "anti-matter blotches" throughout space. In order to warn travelers about the blotches, they've stationed "lighthouses" in their vicinity. One of the lighthouses loses its position and drifts into our solar system. Two earthmen investigate the lighthouse and become prisoners when the lighthouse is retrieved by the Kull. They find themselves caught up in a gambit between the Kull and their enemies, the Zarran. |
