PC gamer posted an article that makes an interesting counter point to the article FFG recently posted discussing the insertion of major characters into your game.
The FFG article by Bryan Young makes some good presentations about how a character of legend can help ground a campaign in the setting, and suggestions on how to stat such a character.
PC Gamer's Jody MacGregor seems to go the opposite direction, providing examples where a character of legend damaged the story either by not being sufficiently legendary, or by being so legendary the players looks like pointless chumps and super janitors.
So what's the call? Should Ahsoka show up? If so, how do you make her more then just another quest giver? What can she actually DO that keeps her character intact without making her look awkwardly helpless, or leave the players holding the mop?
I of course use Ahsoka as the big red example, but can you include any character of legend is really my question.
