Jack continued to follow Master closely. Despite his dislike for the ethereal, Master proved to be quite stealthy.
Master was patient and cautious. He only moved when he was sure the path was clear. He watched all the red dots on his radar and memorized their movement patterns.
Master's God-eye monocle was special compared to the others. While Jack's one had the dots on different elevations all moving around in his two-dimensional radar, Master's one could be set to different elevation levels. He could set it so the radar only showed the ones currently on this level. He could also set it to show what's on the level above or below if there was any.
In addition, his radar also worked as if sonar. The layout of the corridors around him was mapped out on his radar as he moved.
