Name: Firen Blade
Race: Human(oid). You're not going to notice any difference next to any other essentially human extraterrestrial species (and there seems to be a metric ton of them), and what does set them apart isn't so spectacular next to, say, teenage, magic-sucking, spell-spitting mercenary high school students with memory-eating superbeasts possessing their hearts. They eat like humans, they sleep like humans, they walk like humans and they reproduce like humans. Aside from some minor organ shuffling, they might as well be humans. They're naturally strong and tough, but nothing that's going to stand out next to the less natural but far more commonplace ways that humanoids throughout the worlds make themselves strong and tough. They have a remarkably high magical potential for a race that never developed magic culturally, and this is thought to be due to the generations-long overarching influence of the being that fed upon them.
Appearance Lean and highly toned, Firen looks like he was raised on a steady diet of hard running and empty dust. He doesn't reach gaunt levels, but there's an impression he could have been bigger with the right diet and exercises. He wears a very faded red leather jacket over a black shirt, military khakis with a paracord utility belt and military boots. His utility belt looks like something out of World War One, complete with a can or two of tack, a dated canteen, a small first aid kit and primitive smoke bombs. The sword that he wields in one hand or sheathes on his back would, with its four foot blade, only just be classified as a claymore on Earth. With shaggy auburn hair and piercing eyes, he'd be a looker with a sponge bath and an updated wardrobe.
Personality Firen is an extremely focused individual, unwilling to sway his path for anything less than the most dire and demanding of reasons. His home planet going pop did not qualify. After the Heartless were drawn to the being preying on his people and the subsequent destruction of Centas, that being his home planet, and assuming the being was also gone in the process, his intense focus and revilement has moved to the Heartless and he intends not to let such a thing happen again if he finds it within his power to stop it. Raised from childhood as a soldier and a cool-headed, highly focused Sword Saint, these only conceal a deep, burning fury for justice and redemption.
History Centas was doomed even before the Heartless came. Well, no, that wasn't entirely correct. The planet would have been fine, maybe even its ecosystem, assuming it had eventually recovered from war. But its people had been on a downward spiral toward oblivion for nearly two centuries. A monstrous being had descended from the stars and set about their destruction to sate her own hunger. Like an empathic vampire, she fed on hatred and anger, making the brave but emotional warrior people both undeniably satisfying and incredibly vulnerable. Their greatest warriors, the ones they had the most pride in, were their berserkers, who channeled their rage into incredible destructive power thought to be divine. But their most defining trait betrayed them against this foe, and they fell almost too quickly for the Centasians to realize what had gone wrong.
As the war raged on, they learned to restrict their emotions more, for the sake of their own survival, and a new warrior rose to replace the Holy Berserker: The Sword Saint. Instead of unleashing furious wrath, they focused their destruction into a laser point, dismantling their foe with surgical precision until it lay in pieces before them. These almost monastic warriors were fielded alongside more traditional troops in the battles against the invader's seemingly endless hordes.
But by the time the Heartless arrived, the inevitable course of the war had become undeniable. They were a mere tipping point to a far more violent conclusion than would have happened anyway. The Centasians had never really earned ground against the invader. They hadn't held her off for generations through sheer grit. No, they lasted as long as they had on no outstanding merit of their own, but that it was simply the pace of the invader's appetite, and Firen the last crumb blown clear of her plate before she had swept him up, too.
Name: Furious Soul
Appearance: With Firen's strong attachment to his own sword, it's little wonder that Furious Soul resembles a key form of that weapon.
