My Gluttonous System

Far in the past, human civilization faced the greatest crisis. The world that these humans lived in was deteriorating at an alarming speed as global warming and volcanic eruptions became the norm. Millions of people died yet no one could find the solution. They thought that their end was set in stone, until… Mysterious gates started appearing around the world. These magical doors linked between earth and many other worlds from all in the universe creating a new hope for this powerless race. This revelation started the 'era of crusaders'. Humans with unnatural powers that entered these gates to discover their mysteries and attain whatever they wanted. Unknown ores, weapons, creatures, and all kinds of magical artifacts. It was the dream that humans thought was going to last forever…But, what they didn't know is that dream was nothing but the prologue to a nightmare. A nightmare they will never wake up from.
