satisfying ways to end a story

After years of perpetrating heinous acts, our main character, Desmond, becomes weary of his violent path. Yearning for a normal existence, he embarks on a journey to shed his old ways, only to be thwarted by the whims of destiny. Through an untimely demise, he is granted a remarkable opportunity: a second chance at life in an entirely new realm—a realm where magic reigns supreme, tightly controlled by a formidable Wizard who holds the threads of fate in his hands. This unfamiliar world teems with diverse races, including Demons renowned for their prodigious physical strength and Elves who command unrivaled mastery over magic. Even the most ordinary creatures have evolved to harness formidable magical abilities. However, our protagonist is reborn as a human—the frailest and most vulnerable of all the races. Can he navigate this tumultuous realm, where peril lurks at every turn, relying solely on the wisdom garnered from his past experiences? "To survive in this world, I will do whatever it takes, even if it means wiping out an entire race."
