The Engine of Oblivion
Oblivion, an embodiment of forgetfulness was filled by an Artist, who could never remember the right mixtures for his paints. Although this was a meaningless and trivial problem at first, it eventually led to him developing a memory loss, and slowly drove him mad. But he always forgot why. And every time, he would go on a rampage, destroying property he could get his hands on, injuring people, animals, anything that stood in his way. Eventually wandering back to his home, forgetting his deeds and wondering why everything in his life felt so isolated. He died in relative obscurity, only some of his works being preserved without name. Sooner or later upon this death he was of course contacted, and formed a contract, therefore becoming the Engine of Oblivion.
