Okay, I've got two possible human concepts now, and one warforged concept coming later. I've gotta run out to a comic book convention in a minute, so that'll probably take until much later tonight to show up.
Lhulan Ceth, the Reformed
Lhulan Ceth was born in Sigilstar in Thrane, just one of too many children for his parents to support. He spent his days avoiding school and his nights seeking ever more dangerous and forbidden amusements in the ciy streets. He joined a gang before he was 13, committed murder before he was 16, and became incarcerated before he was 18.
Oddly, he became a model prisoner. The authorities were now the strongest force in his life, just as his local gang had once been, and so he gave over his allegiance to them wholeheartedly. In Thrane, of course, this also meant giving over his allegiance to the Church of the Silver Flame.
Lhulan was bright, talented, and a useful snitch on everyone else in the prison, so the Church began to take interest in him. Eventually, his early release was arranged, and he obediently entered training as a templar of the Flame.
He was placed under the authority of a Cardinal who also supported the Lodge of Glory, and gradually proved himself both eminently capable and obedient to the letter of the law, even to the point of reporting to the Cardinal on the errors and heterodoxies of his equals and immediate superiors.
Gradually, he was employed for ever more sensitive and internal matters, until it was decided that he was fit for service in the Lodge itself.
Lhulan Ceth, the Scholar
Lhulan Ceth was born the first son of an educated, upper-middle class family in Aundair. An intelligent but essentially aimless youth, he went to university as was expected of him, and discovered an interest in history and theology. In the course of his studies, he journeyed to Thrane and eventually Flamekeep itself, researching the times of Tira Miron and the spread of her new faith across a land which once revered the Sovereign Host. Lhulan himself had been raised to observe the older pantheon, but although he never felt any special connection to it, the rapid conversion of an entire nation away from the predominant faith of Khorvaire seemed almost unbelievable to him.
It was through these inquiries that Lhulan learned of the threats that the Church had been formed to combat, many of which were still as alive in his day as in those of Tira Miron. And the more he learned, the more he began to feel that the Silver Flame burned in him as it did in the people of Thrane. The world was a dark place full of ancient terrors, and the Flame was vital to light a place for frail, mortal humanity in it.
Lhulan Ceth, burning with the zeal of the converted, quit school and joined the Church of the Silver Flame. While officially a friar, he was employed by the church not for missionary work, but for the same research that had brought him to Thrane: He became an expert on church history and relics, and they sent him all over the nation--and occasionally beyond--recovering knowledge and artifacts lost in the War.
At times, Brother Lhulan was unsettled by what he saw. In some parishes, the Church's representatives had become lax, permissive, even corrupt or heretical. He reported quietly and promptly to his immediate superiors on every infraction he found evidence of. Those superiors found this good. He was never officially made any kind of inquisitor, but he was increasingly assigned to areas of less historical significance, and more suspected malfeasance.
This practice nearly cost him his life. Eventually, Brother Lhulan discovered a deep infestation of one parish by agents of the the Lords of Dust . . . and they discovered him. He was ambushed by a squad of hired blades, but while he nearly died, he managed to dispatch them by himself.
Then the Lodge of Glory took an interest in him.
