User blog comment:General MGD 109/How was Sigan killed?/@comment-3325613-20120119131037

I'm not sure about how Sigan was captured (but I support the theory of other sorcerers involved) but I was thinking about the warlocks Uther put to death during the Great Purge: maybe they were so scared when the guards captured them that they couldn't use magic. What I mean is that, except (as usual) skilled sorcerers like Merlin, Morgana... other magic users cannot focus their powers properly when they are emotionally (frightened)-charged and they don't have time or the necessary instruments to perform decent magic. So I guess surprise is the best weapon against a sorcerer.
