Tattoos, Luck and Addictions (spoilers all RotE books)

[Nuytsia]

I suspect we weren't told what those 2 previous tatoos of Kennits were, but I really can't be sure. I am just about to re-read the Liveships books, so I'll keep an eye out for any more clues!

In relation to the Fool and Elliana's tattoos...... I never really understood why the PW uses dragon tattoos? Am I clueless, as this seems a fairly key point. She wanted to prevent the return of dragons didn't she? Sooooooo, why did she use dragon tattoos?
Also what exactly was the purpose of those tattoos? She had power over Elliana through some sort of mind link - the Skill or something directly caused by the tattoo? What does this say about why she had the tattoo done on the Fool???

Re addictions, I don't know what exactly we are to make of the addictions of Fitz, Chade, Burrich, etc as far as a unifying theme ..... except that it just occurred to me that all those with addictions are male???

I always thought the Forged ones were based on real life addicts .....
