Back then, the world was a dangerous place, filled with monsters feasting on the dark depths of magic, growing more and becoming much more frightening and dangerous. But not only the creatures managed to learn and use the magic they found. Some humans specialized in certain ways of magic, too, protecting the villages from ravaging creatures. They were paid for every creature they killed. Not everyone could become a mage, so they were highly looked up to, but not all of them were as noble and pure as they would appear. Some of them were filled with greed and would release creatures upon cities only to dispose of them later, to receive more payment. Others would leave the city, living in the wilds, looking for the dark depths of magic, driven by an insatiable thirst for power.
As time went by, the greed of the mages grew larger and they demanded more money, despite having practically everything they wanted. The king at the time grew tired of having to pay half-baked mercenaries to fend off creatures they themselves released upon his cities. He called for the strongest mage in the lands, a scholar that studied and experimented with magic, one that never used magic to kill. This man knew nearly everything there was to know about the magic of this world and he could fulfill the king's request. To dispose of all the magic in the world. The scholar said no word, he simply nodded, then turned around and walked away.
The scholar knew why the king requested this and he agreed with him. It took him several months to create what was needed to rid the world of magic, but he did it. On a day like any other, nobody saw it coming, the scholar opened a portal to another dimension. The portal sucked in anything that held magic, along with the mages, pulling stronger on things that held more magic. Slowly but surely, the amount of magic in the world lowered until nothing but a few relics remained. Magic had become a very rare thing and none of the items that remained were strong at all. Time passed and most of the magical items had been used. Only a few remained, mostly in ruins of caverns of buildings that collapsed before the magical items could be used.
After centuries of living without magic, humans had forgotten all about it, save for several legends and stories, though nobody believed them anymore. They had managed to live without it and the wildlife has grown less dangerous due to the lack of magic. There were several legends, all differed depending on where the storyteller was from, though one was told the same everywhere; it was the most popular one, too. The legend about the scholar who rid the planet of magic.
