Omniversal Travel

A young man who lived his entire life under the yoke of others finally finds release from death after months of torture. As fate would have it, he ends up reincarnated in the world of The Witcher as a villain destined to die at the hands of the protagonists. Deciding to take his destiny into his own hands, the ambition to master the gift of traveling through the Omniverse and exploring its infinite worlds is born within him.
The protagonist is someone who will not hesitate to commit heinous acts if it means achieving his goals despite showing himself as a serene and kind person most of the time.
This is my first fanfic and there will be NO harem, just some girlfriends from time to time.
