Over the planet Typhar set its main sun - a flaming, hot, white-yellowish star. Thanks to its energy, which the locals learned to comprehensively use, there were no cold poles on the planet, there was enough heat and light everywhere. When the hot ball disappeared overseas, imperceptibly melted in the ash haze of the horizon, the darkness did not begin to thicken, the moons did not shine. It's just that the twilight light over the ocean that has quieted in the snow has become a little different, somehow greenish-mysterious.
