Though it had been like this for 2 years now, Shirona still found it strange. Far above her, a thick ocean of crimson completely blocked out the sun's light, and yet the atmosphere felt temperate. It was even bordering on unpleasant, as summer approached the tropical town. Of course, you couldn't tell it was summer except by the temperature and the cries of the obnoxious cicadas, which she was silencing with her knife. She was stood in the rebellion group's "fortress", which was built by stretching string between some of the peculiar algal blooms and letting said algae grow along them until they formed walls. Why, you ask, does a covert rebellion group hide in a huge structure? The answer to that is quite simple. There is a complete absence of light except for in the cities. Even the rebels have a hard time finding it if they leave. Or at least, that was the case until recently. As Shirona was briefly explaining the setting to the readers, a large and horribly bright spotlight was shining on the building, its beams strong enough to penetrate the walls and illuminate the interior too. From the looks of things, the local demon organisation's intelligence group had finally found them. Shirona strolled briskly through the small above-ground segment, then descended a flight of stairs into the twisting labyrinth that made up the sub-surface complex. As she did so, a surge of 3000-degree flame washed over the stairs with such energy that it didn't even bother following the angle and instead simply melted the rock on either side until where the stairs formerly were was now a solid block of stone. From the faces of the others who managed to get to the entrance in time, she could tell that a great deal of the resistance movement had died in the demon's attack on their HQ. The more hardened faces showed only hope that enough of their wielders had survived, for it was clear their options had just been reduced to one: the resistance had no choice but to go on the offensive in an all-or-nothing gamble to reclaim their home. Just as Shirona was thinking that, an elderly man who in the dim electrical light she could just about make out to be the resistance's second in command, spoke up after clearing his throat. "Um, as you all may have gathered, the oppressive monsters have just destroyed our home." He spat the words out with enough venom to kill several metaphorical elephants. "We don't have the labour to hold out anymore, so first thing tomorrow morning our remaining wielders and soldiers will take all the celesticite we can find and will obliterate our town's infestation." The word 'morning' stood out to Shirona. Even without the existence of daylight, the humans still had a definite day-night cycle. Nowadays, it was based on the habits of the demons, who do not actually sleep, but who show a marked reduction in speed and strength for around 8 hours in every 24 hour cycle. The start of this period marks "morning" for humans, and seems to be independent of any external factors.
