Merlin's Apprentice: Vengeance

After his adopted brother betrays the kingdom, murders the royal family, and seizes the throne, a fallen prince returns from death seeking revenge. Merlin, the God of Magic, accepts him as his only disciple and trains him for years. Believing he is still merely a novice, the prince returns home cautiously, determined to reclaim everything stolen from him. What he does not realize is that his magic has already surpassed mortals and reached the realm of gods.
