Sigan was not destined to be around at Merlin's time. He WAS the most powerful sorcerer to ever live. AT HIS TIME. Merlin is now the most powerful sorcerer. Morgana is the most powerful sorceress. No one matches her. (Except possibly in magical combat- she has barely any experience as she has not fought anyone with magic before. Morgause may not have as well, but that's all unknown). Cornelius may have been more powerful than Merlin, but that doesn't matter, he's just the past. I suppose his appearance was just to reinforce Merlin's- what he said to him- how they can rule Albion together. I'm not sure what that suggests, and the producers themselves probably haven't even made their mind up! Happy Wiki'ing.
