Grappling hook level: Redesign start and end scenes

So the magical thread is not occluded by the dialogue. And to give it
more narrative sense:
    
- From the Void runner level, there is an ellipsis.
    
- The StoryWeaver is about to grab a magical thread and be teleported.
    
- But the Void ruins their plans. Has to take an alternative path.
    
- At the end of the level, the StoryWeaver comes from the other
  direction.

Also add a dialogue at the start of the Void + grappling level.
