In the past, four heroes had to fight separately to end the end of the world. Their names were: Demiurge, Hera, Arani and Leto. Each of them contributed in their own way to end the rapid advance of the end of all life on the planet, whose crops were dead, and the sea level was as low as you can get after a day of rain.
However, behind The Calamity there are many untold stories, many lies, and an event capable of uniting these two things.
The truth is that the heroes fought together, yes, only once. In reality, this meeting took place unplanned, a fluke of fate, or rather, a stroke of luck, after all, since the first irruption there is no defined destination for the world, only billions of paths that lead to an even unknown end by the most powerful being in the world. Anyway, their meeting took place at the Citadel of the End, the home of the demons, and together they managed to decimate the demons, or so they thought.
