So here's the main villain of Limitless. Syth is the evil sorcerer responsible for erasing Kaiden's life. Syth is very mysterious and has the strange ability to influence the minds of others. In the beginning of the story he is just a voice that speaks out to the Dark Queen Tessa in private however he later shows himself as the true evil mastermind. But what are his real intensions? He is madly in love with Siroette and will do anything to get her. He also seems to know Kaiden though the two have never met. He searches for the ultimate power, but what does he want it for? Is it so he can control Siroette and the rest of the world? Or is it for something else? Though not much is known of Syth, one thing is for sure, he is a twisted and very insane person who will stop at nothing to get what he wants. Sounds like a villain to me.
