HMm.. Sir Jonathon doesn't seem a match, but those Shadow Knights remind me of...
[sblock=William the Grey]
Sir William Windwalker
Human Male Cleric4/Paladin3/Gray Guard10/Rogue1/Shadowdancer2
Brief Background
Sir William Windwalker is a special knight, trained in the ways of the shadow. The Knights of Shadow are an order of holy men who dedicate their lives to keeping Good people as seperated from the true darkness of the world as possible. They do this by placing their own souls and bodies between the innocents and the evil. As the Shadow stands between light and darkness, so do the Knights of Shadow.
William started out as a normal paladin, dedicating his life to the eradication of "Evil" after witnessing many atrocities of war. He combined his natural Divine talents with his Dedication to become a powerful foe to the enemy... Until he was captured, imprisoned, and slated to be sacrificed to fuel their dark magics. While waiting helplessly for his end, William befriended an elderly gentleman also locked away. Unknown to him, he had just been enlisted in the secretive Knights of Shadow, and this was his initiation.
With the aid of the old man, he was able to escape, and soon became a full-fledged Shadow Knight.
Personality
Sir Windwalker (William to his peers) is steadfastly dedicated to Good, whether it be through Acts of kindness, Eradication of Evil, or whatever. He is a firm believer in 'doing the right thing', even when it's not always the smart thing. (Though that does not, as some have wrongly guessed, stem from a lack of intelligence, merely a belief that if it's the right thing to do, it's probably worth it).
William is not your standard 'stick up the rear' Holy Warrior, and is dedicated to the Spirit of law and Goodness rather than the specific innuendo's of it. As a Shadow Knight, he believes in the greater good, though not to the point of overwriting individual freedoms. There is a very fine line that must be walked between doing what you think is right for everyone, and taking away their freedom to decide that themselves.
The Knights of Shadow believe that by placing themselves closer to the darkness, they keep everyone else safer, and they do the things that the really good people shouldn't have to. Sometimes, if the knight is not pure enough, this can lead to a degradation of character, and some knights have been known to cross too far into the shadows, loosing themselves. It's tough to maintain your righteousness when you're constantly in contact with such vileness, but somehow William has managed to do so... Thus far.

Now of course, that was the ORIGINAL design, I'd have to scale him down to lvl 1, and adjust the background to compensate, but that gives you an idea of what I'm going for...
And btw, COOL on the ShadowKnights, I've been wanting to play this guy for a while (He's been sitting here in my files allready made for a few months).
How's this one sound? Note that the Grey Guard could be edited out if you don't like the prestige class. I originally had the character as just cleric/Pal/Rogue/Shadowdancer, but then when the book came out, my friends pointed out the GreyGuard and I was like "WOOT! Finally I can play a Paladin!"
(BTW, if anything I suggest doesn't fit, feel free to tell me, cuz I've got a dozen character concepts I've been wanting to try, allready written up)
