I like how you run the separate story lines Defcon.
Battlehammer is a driven young …man, who’s family was torn from him by evil. He seeks it out wherever he happens to be and could fit into a crusade easily, (as vast planar rifts created by evil outsider magic destroyed his homeland). And did I see something about an evil dragon cult? Dragonborn were created with the express purpose of routing out and destroying the spawn of evil dragons and their followers

The Church of the Silver Flame would be a natural place for a champion of good, especially one that can shoot silver flames from his mouth

. He might even be considered a prophet or emissary.
On a side note, how different is eberron from standard D&D 3.5? I read the wiki about the system, and the classes look the same, as do the skills (though I'm not sure what the point system you are using is, after every skill roll). Is equipment the same prices and is money the same?

[sblock=History]Titus Moraphim Sebastion's earliest memories were of being spirited away by his family, in the middle of the night. The fiery glow from the burning ruin that used to be their home lighting up the storm clouds of the entire valley. The hooting dark laughs from behind told him it was no accident. His parents and his 5 older brothers were his world, so where they lived didn't really matter so much.
Later there was a tugging at the small boy's mind, he stirred in his fitful slumber, but his mother drew him closer and he settled back down.
A few years later, Titus was ripped from his dreams, by the roar of flames, once again. The family rushed into the night hand-in-hand, but this time the darkness that harried their existence took a much heavier toll than just a home. A tepid gust of putrid breath, a sharp jerk with a wet spray, and his mother torn from his grasp by what seemed to be the very night itself. The oppressive thwumping wing-beats roiling the dust and smoke gave the Sebastion boys a clearer picture of the kinds of monsters that were hunting them. The loss hit them hard for many years after that.
Again that night, a gentle push at the edges of his mind. But in his boundless grief Titus ignored the call, mourning his mothers loss.
His family swore an oath to never let it happen again. They began to train themselves for the invisible war that was being waged against this simple family, always on the move. Joining battle after battle, they fought any opponent that might be linked to the darkness across the lands. As time passed, the Sebastions became legendary soldiers, and simply the presence of one the family seemed to assure victory.
The Sebastion Academy was founded deep in the northern mountains, drawing hundreds of students from across the land. They trained thousands over the next several years, but always in the back of Titus' mind were the flames. They often intruded on his dreams, so when Battlehammer awoke from under his pile of women to the sounds of the citadel's magical alarms, which he had helped put in place, it took a moment to realize what was actually happening - a full scale assault.
The very clouds were melting under the fury of the fiery tides that swept toward the keep. Winged fiends flew through the lighted night, and horrors rode on the backs of great dark dragons belching flaming death to all who stood before them. The hills beneath them black with demons and undead hordes. Magics shot across the skies for hours in both directions and in every color under heaven. Eventually numbers on both sides started to dwindle, then the very fabrics of space started to be rent right in the middle of castle.
It soon became clear that no undead could stand before Titus' might but he could do little against foes not chained to the ground, though the withering hails of arrows from his brothers were doing their part from the battlements. Battlehammer was on the field healing wounds when it happened and could only stare on in horror as the Academy he had built fell to ruin. Parts exploded, other sections simply vanished as the churning black void subsided.
As the sun rose, it was clear that neither side could call this a victory. His brothers were gone, but he couldn't find any bodies. He didn't know if they were dead or thrown across the planes, but they were beyond his reach either way. The throngs of corpses covered the battlefield; some of the undead fell to dust as the first rays of sun hit them.
Titus stood utterly alone amongst the carnage, steam rising from the bodies, the numbness replaced by rage. And this time when the call beckoned there was nothing to keep him from answering it. Suddenly he was standing on a rippling landscape before the great platinum dragon Bahamut and offered the power to seek his vengeance on the evil dragons that had destroyed his life - and he seized the opportunity.
Over the next day he crafted the shell as instructed, sealing himself inside while reciting the words of devotion. Emerging at dawn, Battlehammer looked around at the world with new eyes. His platinum scaled flesh felt strong and strange and new. An odd burning started to coil in his gut and a stream of energy blasted from his lips. [/sblock]
[sblock=Eberron tie-in]After a couple of small modifications to his full plate, He was ready to begin his hunt again. Glancing amongst the myriad rifts that were slowly tearing his world apart. He chose a hole through which he could see a place that looked similar to his own world and stepped through, unafraid.
To his immediate surprise however, he found himself falling from a great height over an expansive forest. He fell for almost a minute before remembering his wings, and unfurling them with a snap of new skin that stung from the sudden stop of his fall. He didn’t notice a town, even from this height, so he turned toward the wooded area’s edge, and tried to take solace in an intact world during his descent.
After a while he noticed a pair of metal lines on the ground. Next to these lines were 3 scout type fellows riding hard, with ghouls nipping at their heals, so he angled toward them instead. With a grand flourish, and a heavy ka-clank he landed behind the ghouls letting loose a roar that surprised everyone (including himself). And lifting his hammer, even as the ghouls turned toward the slower prey, 4 of the 6 were blasted to ash by the might of his conviction. As the other 2 charged to close the gap, Titus opened his mouth and unleashed a sizzling 5ft wide line of silver eldritch flame through both of them. Reducing them to tumbling piles of charcoal that stopped, smoking at his clawed feet.
The riders had wheeled and were returning to the newcomer. Each was sporting a tunic with a silver flame emblazoned on it. Their eyes were wide with disbelief as they came to a stop and raised a hand. They bore several wounds and had obviously been riding for days as Battlehammer’s gaze fell evenly on them. “Dismount soldiers and approach. I can take care of those wounds if you would kindly tell me of place.”
The grateful scouts made camp there for the night, and told tales of Eberron into the dusk, amidst the constant pestering to breath the flame again. They gave Battlehammer thanks in the morning and asked if he would like to accompany them back to the city, to which he humbly agreed.
The city was huge by his world’s standards. The scouts rode in formation around him as they showed him the way to the Church of the Silver Flame. Several townsfolk openly blanched at the site of the platinum dragonoid, but catch themselves as his gracious smile and smoothly eloquent speech put them at ease as he spoke with his companions. Tipping his hat to the lovely ladies on the street. Up the steps to the church and a new beginning. Titus was welcomed into the fold and into a new home. And when the time of the crusade began he was ready.[/sblock]
[sblock=Description]This 6ft6 tall creature is broadly muscled to the point of being lumbering. At a solid 260lbs, without equipment, his platinum scales make him look likes he's actually carved of precious metal instead of living flesh except for his glowing golden eyes. And the tail and wings belay the possibility that he is anything other than a representative of the platinum dragon-god Bahamut, and a force for good. When he speaks, energy occasionally crackles between his sharp teeth. His full plate and shield are well worn from the life of war that this cleric has known.[/sblock]
