In my story Earth is the centre of interuniversal travel, something like the Woods in The Magician's Nephew. To illustrate, in order to reach destination C from A, you will have to go through B, which is Earth. Hopefully that explains it clearly enough. And of course, Earth being the centre of interuniversal travel also means the centre of interuniversal trade, so we're trapped in a millenia-long battle between two other major galaxies, Rodina and Mechta. (sounds familiar?) The aliens travel via wormholes called Lines. These Lines can only be deployed at specific "strange-element"-rich areas. Later on in the story they will be utilized by humans to end the war. Now my problems: 1. How can I describe what happens when you step into a wormhole from a 3rd person point of view? 2. The following is how I described the forming of a Line. I know its pretty bad, but I had tried various other methods of describing and I think this is my best attempt so far. How can I improve this paragraph? I was sitting around a camp fire eating dinner when I heard a loud boom coming from above. I looked up and saw the night sky illuminated in a purple hue. Gasps of disbelief from the camp became very audible. The hue became to contract, forming a long thin line about a mile across. From the forest there came a huge sound of a crash. I stood there flabbergasted. The clouds suddenly became very compact, preventing most moonlight from falling through. It fit however the rumours of the Lines describe it. An alien army had landed behind us. Thank you for your time in helping me out.
