Her clothing is made for comfort and freedom of motion. Long-sleeved tunics and loose-fitting breeches are her norm, accompanied by a dangling sash at the waist, custom boots and gauntlets of black leather, and ruby studs in her ears. A one-piece wrap somewhat like a cowl drapes loosely about her shoulders and upper chest, gathering about her neck. Seheiah's clothing is most often in red shades, being her favourite as well as House colour. She carries a rapier ("Time") and gauche ("Memory"), slung from a belt underneath her waist-sash.

The terrible war no one had foreseen began when Amanthea Suri, of the Emerald House, killed the brother of her fiancée for murdering his betrothed twin, and went hopelessly mad. House turned against House and calyon killed calyon, and Seheiah had no choice but to sit back and watch, for the Ruby House made the decision to remain neutral and uninvolved after one of its members, Seheiah's close cousin Cerebus, acted on his own and rescued the mad Emerald princess from imprisonment in the Onyx castle.

Seheiah grew restless as the war continued, having nothing to do besides sit back and watch the members of the other Houses die as no immortal should have to. Time passed slowly for the unoccupied calyon, whose fiery nature wanted her to be out fighting--many of her friends from other Houses had been killed, but the neutrality of her House would not let her do anything about it.

Finally, Amanthea fled alone into the Seica Mountains, and the war suddenly stopped. Seheiah couldn't comprehend it. Thousands of calyons had died because of the betrayal in Amanthea's marriage, and the Ruby youth couldn't understand why the war had simply stopped just because Amanthea had gone away. She decided that the risk of the Emerald returning and starting up the chaos all over again was too great to go ignored, and resolved to make sure it wouldn't happen. She followed Amanthea to the mountains several weeks later, intending to slay her. Instead, Seheiah underestimated the mad Emerald, and was taken prisoner.

Seheiah wasn't the only one. Slowly Amanthea gathered up not only more calyons, but lycanthropes and dragons as well. Never could she have guessed what the Emerald's intentions were, for even her best conjectures were impossibly far from the truth. Caught into some horrible experiment that Amanthea had plotted, Seheiah was one of the first to be force-mated to a creature that wasn't even of her own species.

She lost all track of time after that. Seheiah became little more than breeding stock in Amanthea's plans to create some new, powerful species to unleash on her calyon kin. Ravaged in both body and mind by the unnatural breeding, Seheiah was struck with a horrendous rage with the birth of the first of the hybrid beasts that would come from her womb. She would have killed her first child with her own bare hands had it not been quickly taken from her reach. Seheiah hatred of what she was being made to do so was so intense that it was almost a madness as horrid as Amanthea's own.

With her second pregnancy, depression joined the ravaged mix of Seheiah's emotions, and she constantly swung between misery and ferocity. She never noticed that her fellow calyon prisoners were dying under the same abuse, and time became a slow blur for her. When Amanthea's experiments were complete, the Ruby was one of the few Calyons left alive. Of perhaps a thousand or more calyon prisoners, no more than ten still lived. Amanthea's creations, the chyriths and the mazdivs, now possessed firm bloodlines and so Seheiah was no longer force-bred, but neither was she allowed to go free. She had nothing to pass the time but daydreams of violent, bloody revenge.

The chyriths and mazdivs were just as much a prisoner as she, however, and one day they finally revolted against their mad creator. Seheiah's cell was broken open in the ensuing chaos, so she fled the mountains and reclaimed her freedom.

Her depression was allayed somewhat with her unexpected freedom, but her rage leapt forth to take the places it left empty. She wanted to make someone else suffer the way she had, and so turned to the bounty-hunting assassins simply called the Hunters. Joining their ranks and taking on the Hunter-name of "the Hellwraith," she soon had a horrific reputation: if you wanted someone dead and wanted them to die in excruciating pain, the Hellwraith was the one you wanted.

But time eases all wounds, and immortals have no lack of this numbing balm. Seheiah's rage and depression both wore themselves out as millennia passed, and though they never went completely away, she did learn how to smile and laugh again. The only part of her horrible ordeal she was unable to release was her hatred of Amanthea, and her desire to see the Emerald suffer a thousand agonizing deaths. She never again attempted to kill the mad calyon herself, however, for Seheiah feared Amanthea just as much as she hated her.

In her time of recovery, Seheiah also developed a hobby of world-walking. Unable to look upon her brethren, she made no attempt to rejoin the recovering calyon community, and the stable, growing populace of chyriths and mazdivs made her uncomfortable anywhere else she went. The only places she could go to escape having solid evidence of her past flung in her face was off-world, where the chance of her running into a calyon, chyrith, or mazdiv was slim to none. Chytonia remained her homeworld, however, and always called her back after a century or so.

Eventually the world learned of a prophecy: though Amanthea, now more often called Suri, was now held in frozen, blood-starved stasis in the mountains where she had once had her mad reign, there came a foretelling that one day a chyrith would go and awaken her, and a new war would take the entire world. This did not bother Seheiah much, as she was assured that most of Suri's creations still hated her and would fight her to the death should the prophecy ever come true, and she could always retreat offworld until the war ended.

What did bother her was when she later learned there was a calyon whose only goal in life was to cure Amanthea of the insanity that had taken her. She doubted one man alone would be able to "save" the mad Emerald when she woke, but since Seheiah believed Suri didn't deserve any kind of redemption, neither would she allow it a chance at happening. She located the warren where this calyon, an Opal named Leosetryn Kamiyarith, slept in a stasis similar to Suri's.

Since he was an innocent and his intentions were well meaning, she did not simply kill him were he lay. Instead she crafted a portal to a world called Mythicalae, and brought the dormant calyon through the magic gate with her. She'd been to Mythicalae before and had signed up to participate in their Wyld Hunts, for entertainment if nothing else, and bringing him along to a distant world separated him from Chytonia just as well as killing him would have done.

What she hadn't considered, however, was that the other calyon would doggedly follow at her heels after being woken from his stasis, right into the Hunts she was scheduled to attend.
