When I mentioned Ayden becoming a Harper, I guess I should have clarified it a little more. I don't actually plan on him taking the Harper PrC, at least as of right now I don't, but I meant it more along the lines of him just being a field agent for them, doing good deeds where he can, helping out the weak against the strong, basically what we are doing right now.
Kirinke, I'm not sure if it will help any, but I'd like to make a suggestion for you about Teleri. Look at her right now as she stands, and think what you would like to see her become down the road. Don't think what would be "cool", as right now almost everything could seem it, especially if you are on the fence about which way to go. I stepped into the Human Paragon sub-class, because I wanted to be able to show that as Ayden grew in his faith, so also did he grow as a "champion" of his race. It wasn't an easy thing to do, as at the time, we really needed all the clerical support we could get, and to be honest, Ayden is not the easiest char to play in a combat heavy world.
You have structured her stats differently than I did, allowing her to be a stronger "arm" of the church, and if you begin to tweak that, especially with the blade that you now carry, it would, imo only, weaken what you could build. I see Teleri as being an almost true mix of fighter and priest, at lvl 20 she could easily read Fig 8/Pr 12. This would show her continual spiritual growth, as well as the fact that she has had to keep her battle skills honed to protect not just herself, but her companions as well.
If you want to take the Neg feat, please do, as every "face" person a party has is a benefit, but look back at the posts and ask yourself "Did Teleri talk much? Has she been an active voice so far? Or is she now just preparing to show these hidden skills?" As I am all about the progression of chars through their past actions, a fact that I think will one day cause Sielwoodan and Ayden to get into a fist fight...

, I personally don't think that feat is right for you. Do I think Iron WIll is, definately, as it could show her resolve at not allowing others to dominate her mind if she can help it. Plus, I think it is on the Fighter's bonus Feat list, while I know Negotiator isn't, a fact that would make you have to wait until 6th level to take, and by then, it might make perfect sense for her to take it...
Sorry if I am rambling, but I see you all doing amazing jobs with your chars. I love the fact that while Sielwoodan can be an arrogant prick, he's our arrogant prick. I love the fact that Drogo has not lost what I consider his "halfling charm" even though his progression as a stronger druid may make him one day have to choose what is more important to him, his calling or us? Calenthang's odd personality quirks that just pop up moments before the smack down begins, I swear it is like we have our own set-up music..
I'm sure you all get the idea, so I will shut off the rambling valve and get back to the heart of the matter. Only you can decide what you want to do to Teleri, and we will support your decision along the way. Just be sure that what you do with her, you do because you want to do it long term, not just because at this moment, you are having a crisis of faith...
*steps off soapbox*
And as always, it is a blast getting to play with you all...now lets kick some arachnid ass!!!
