[ WP ] The Earth does not rotate . One side always faces the sun and is in continual daylight . The other side is in eternal night . Cultures on both side develop around this .

`` The Colony on Gliese 765 was founded 475 years ago today!'' screeched the announcement on the speaker. The official name for the planet was Gliese 765b, but everyone here called it Coin, as in two sides. 
 
 `` Happy Foundation Day!'' screeched in follow up, and the familiar patriotic music followed that was ignored by everyone. Max looked out the window of his office, which had an impressive view of The Curtain. And saw the relentless winds blow some paper into the sun. 
 
 Coin was tidally locked, and the hot side, which never knew night, was where everyone's power came from. Max's job was to monitor the transmission lines that fed power to the night side where everyone lived. Power was cheap, and life on Coin was all about the size of your heater. The Curtain was where the two side met, and was constantly being pounded with gale-force winds as the light and dark sides of Coin worked to balance the temperature on the planet. 
 
 Hardly anyone lived on the bright side, it was too hot and oppressive, but the people who worked on the solar arrays there managed to have a few little air-conditioned burgs. Most days, Max was bored. The power lines were established hundreds of years ago and were over-engineered. They were not efficient, but it did n't matter, there was never a shortage of light from the horrible red star and like usual, all the lights were green. The power lines never went down, but occasionally did develop noise that could create power surges, but Max hardly ever saw signs of that. 
 
 By the time the Foundation Day tune stopped, Max had grown bored of watching the winds of the Curtain buffet a pair of workers as they got into their cab of the monorail. Their destination one of the many cities on the night side, to be sure. Max's shift did n't end for hours. maybe he would cheat a bit and watch a vid. He was n't supposed to, but when the Supervisor was n't around, the only person in the facility was himself. 
 
 Max had been watching an old series about Earth. Earth was a proper planet that had day and nights and weather and a moon and a star that did n't look like a boil. Not that anyone ever heard from Earth much anymore, apparently for the past couple of hundred years, there was some sort of ecological disaster there, Max did n't know the details, it did n't matter, the vid's story was set from before the Diaspora when electricity was n't discovered yet. Max watched it with a longing that he felt in the deepest parts of himself. There were animals, green grass, and women who's only concern in life was which wealthy man they wanted to marry. The world just supported them, not like on Coin, where every inch of life needed to be taken from the light side and carved out of the ice on the dark side. Max liked to imagine himself as a farmer. 
 
 There was an alarm. It was strange to hear, because Max had previously only heard it on training vids. He looked over at the console and saw that there was no power on his lines. Something had gone terribly wrong. There was no power! Max tripped the alarm and got on the phone with his contact at Solar Array 42. It rang and picked up. 
 
 `` Steve! Steve! Are you there? What is going on?'' 
 
 `` Max! They've set off bombs!'' Steve replied. `` They are shutting down the power to all of Coin! 
 
 `` Who?'' Max yelled the question. The lights from the street outside started to go out. 
 
 `` They call themselves The Liberation Army of Gelise. They are-'' the line went dead. 
 
 Max looked up and the lights went out in the office as well. The only light coming from his badge and communicator. Outside his window, the only light was being belched from the north, all power was off. Max knew from his training, how much time there was to restore power before the night side froze, 3 days. Max also knew without the monorail, nobody from the night side was going to be able to get to the borderlands, where you could live if you could stand the winds. 
 
 Max knew what he had to do, if Coin was going to survive, he needed to get the power back on.
