It was seven years earlier that Cassandra witnessed a mysterious Asian woman bring Sophitia back and draw out shards of the evil sword out of her sister's flesh while treating her wounds.
Therefore, when Sophitia disappeared again a few years later, Cassandra was certain that her sister had left to contend with Soul Edge once more. One day, after running errands for her family's bakery, Cassandra visited Sophitia's home. There she saw a familiar metal shard. It was undoubtedly a fragment of Soul Edge.
Angered by her sister's panicked reaction to the shard, Cassandra ran to the Hephaestus Shrine.
"Why are you doing this to my sister? How can you claim to be an almighty god? Answer me!" Cassandra screamed.
Her voice reverberated throughout the desolate hallowed grounds. Cassandra collapsed on the floor, worn out from shouting. It was then that she saw the metal fragment resonating with the holy sword blessed by Hephaestus.
She realized then that Soul Edge was still alive. But she could not allow her sister to carry the burden any longer. Around the time when light began to filter in from the eastern skies, the holy weapon disappeared from the temple.
Determined to destroy Soul Edge on behalf of her sister, Cassandra left her home. In the mountains to the east, she happened upon a city where the residents had lost their minds from the effects of evil energy.
"What's going on?" The fragment she held reacted strongly to this place. Soul Edge was somehow involved in this bizarre phenomenon. She made up her mind to free the city.
"My sister was able to do it… I can, too!" she said to herself. But then something unexpected occurred—cracks appeared in the sword and shield she had taken from the temple of Hephaestus.
Feeling deeply apprehensive, there was nothing Cassandra could do but to flee the city. She felt completely helpless—she may have used her sword and shield a bit roughly, but she couldn't believe that arms made from holy ore could be damaged.
As she gazed at her damaged sword and shield, the image of her sister and her young niece and nephew flashed through the back of her mind. Her sister smiled happily, leading her children by the hand…
"No... I can't give up." Cassandra's eyes shone once again with determination. She returned to Greece to consult with her blacksmith brother-in-law, Rothion. Unexpected news was waiting for her upon her return home, however.
During Cassandra's absence, Sophitia had once again set out on a journey to destroy Soul Edge.
"Damn you, Hephaestus! This is all your fault!" Cassandra cursed to herself, though she didn't consider her sister having regained her previous strong will to be completely bad news.
She had to help her sister. She would stand by her and support her.
After receiving a new sword and shield from Rothion, Cassandra set out with a pure purpose in her heart, with the early dawn’s soft light shining upon her back.
Cassandra set out once again for the town she has visited before Eastern Europe, hoping to find more clues that would lead her to Soul Edge. But as she hurried through the night, a man appeared before her. His eyes were stained red; she was reminded of the story she had heard about a swordsman who had led the mad townsfolk.
"You have a piece of Soul Edge, don't you? I can feel it," the man said, and in an instant he was upon her. After a hard fight, she was able to finally land a blow on her assailant, but he only sneered at Cassandra and vanished, "So, girl, you can ward off evil, though not as strong as the Holy Stone. Interesting. I'll let you live... for now."
"You're going to run?! You coward!"
A laugh echoed around her. "I already have what I came for." Panicked, Cassandra searched her tunic, but the fragment of the cursed sword was gone.
Unnerved at first, Cassandra pushed those unhelpful feelings down and headed for the town, where she discovered some townsfolk still retained their sanity. In fact, they had been healed—by shining blue crystal. Could it be the Holy Stone the swordsman had mentioned? She set out to learn more, and then a rumor caught her attention: a man carrying a mass of crystal as tall as himself was on his way to Osthreinsburg. If the crystal he bore had the power to smite evil, then that could only mean some evil presence lurked in the ruined castle there. Was it Soul Edge?! Cassandra decided to follow the man to Osthreinsburg and find out.
Cassandra does not know that she's following Soul caliber, the spirit sword that was made to destroy Soul Edge.
Eventually, she infiltrated the home of the cursed sword, Osthreinsburg Castle. But who stood in her path was none other than Sophitia, who surrendered to the evil sword after her daughter was taken hostage. Cassandra was so shocked, that she was knocked out unconscious from a single strike from her sister.
By the time Cassandra woke up, her surroundings were warped into a strange place. With the destruction of Soul Edge, the Astral Chaos that corrupted the castle began to contract quickly. Dragging her injured body along as she looked for Sophitia, she finally found her sister's collapsed body in one of the castle's rooms. Cassandra rushed over there instantly. Just at that moment, a rift to another dimension opened in front of her eyes.
Cassandra found herself in a new dimension, completely bewildered by what she saw. Though despite this, her mind remained only on the safety of Sophitia. She decided to push forwards through this new realm, Astral Chaos, in hopes of finding an exit and save her sister as soon as possible. However, such an exit seemed to never come.
So much time had passed that Cassandra had completely lost track of it, soon even forgetting her own name. Her hair turned grey with worry as all that dwelled on her mind was the safety of Sophitia. Suddenly, however, a portal opened in front of Cassandra and she stumbled her way out. The only figure to stand before her, was none other than a younger version of herself.
Although she attacked the younger Cassandra ferociously, she was unable to find the will to win and found herself unable to continue fighting. With a final plea, Cassandra pleaded to her younger self to save Sophitia through any means necessary, and informed her about the shard of Soul Edge lodged in Sophitia's heart.
Before she could hear the other Cassandra's answer, there was a bright flash of light, and she was gone.As the daughter of a baker in Athens, Cassandra worked hard in order to support her mother, who had fallen ill from anxiety. Three years had passed since her older sister Sophitia returned from her holy quest to destroy the cursed sword. But one day, with her wedding drawing near, Sophitia once again vanished, leaving only a note behind. Cassandra was content to look after her troubled mother, who was quite close with her errant oldest daughter, until she realized why Sopihita disappeared so suddenly...
Almost immediately, Cassandra thought of places where her sister might've gone, and her mind turned to one specific place. Half-convinced her theory is correct, Cassandra sets off at a run. Her destination: the ancient ruins of the Shrine of Eurydice. It was there that Sophitia, after her battle with the cursed sword, had returned the holy sword and shield entrusted to her by the gods.
Once Cassandra arrived, however, she found that Sophitia was nowhere to be seen. Instead, the area was consumed in a purple hazy glow, and Cassandra saw a large portal open in front of her. A figure stepped out of the portal, seemingly in a trance, with silver hair and a face covered by a small mask. The oddly familiar figure attacked Cassandra without second thought.
In self-defense, Cassandra retrieved a sword and a shield from the Shrine, and prayed to the gods. The gods answered her prayers, granting her the power to wield her sword despite never having done so in the past. After a difficult battle, Cassandra found the will to defeat her enemy and remove the mask from her face. With all doubt removed along with the mask, Cassandra now knew who stood before her.
The swordswoman who looked exactly like Cassandra began to speak hesitantly of Sophitia, and about a prophecy of a future dark and cruel. "Sophitia's child will be born with a great darkness inside, and will be abducted by the cursed sword's Malfested kin to become Soul Edge's vessel. The child will become unable to live without the sword's evil, causing Sophitia to remove the fragment of the cursed sword inside her and use it to save her child..."
Cassandra, more than anyone, understood what this prophecy meant. Sophitia had a fragment of the cursed sword inside her, a secret Cassandra never revealed to her family, Rothion, or even Sophitia herself... But before any more words could be spoken, the other Cassandra vanished, leaving behind only her mask. Cassandra took the mask for herself, and vowed to save Sophitia no matter what.
Cassandra visited the neighboring town's smithy, a place run by the young smith Rothion. Her interest in blacksmithing-and in learning about her sister Sophitia's lover Rothion-meant she'd stopped by here a number of times before. Of course, this was the first time she'd visited since her sister had left on her second journey. Her objective, of course, was to see how far Rothion had come on a certain project.
After her confrontation with Rothion, Cassandra is filled with frustration and rage. She returns to her daily tasks helping—her family at the bakery, but she can't put her heart into it. "If I fight in Sophitia's place, then she can find happiness." This thought comes to her time and time again, but unable to act on it, her wordless irritation grows until it is on the verge of bursting...
With her brother Lucius's help, Cassandra gets permission from her parents to leave home for a while. But in truth, Cassandra is resolved to fight Soul Edge and its malfested kin in her sister's stead. Her excuse to leave was to search for her sister and gather ingredients for new recipes, so she would have to stop back home now and then, but that was good enough for her purposes. Of course, she kept the fact that she was borrowing the shrine's divine arms again secret from Rothion.
Cassandra's gained some confidence from the battle with the cursed sword's kin. Praying that she'll bump into her sister somewhere by chance, she continues to roam further and further in her search. Although her pace isn't fast, she has the feeling that she's getting closer to Sophitia. This feeling is just budding in her heart when Cassandra gets a request.
Cassandra discovered an evil and unscrupulous cult after Sophitia, and unexpectedly potent power from her divine weapons. After barely escaping a deadly trap, doubt clouded Cassandra's heart. Why did Sophitia sacrifice her own happiness to take this dangerous journey? Unable to find an answer, Cassandra returns home and reveals her worries to her younger brother, Lucius.
Hearing from Lucius that a swordswoman resembling Sophitia had been seen heading towards the Shrine of Eurydice, Cassandra left again to search for her sister. There was much the two had to discuss, both great events and numerous thoughts and feelings. Cassandra was troubled-how should she approach her sister? Where should she begin? Cassandra's journey to help her sister find happiness was finally headed for a destination.
With Sophitia safely back in her hometown of Athens, peace returns to the Alexandra family. Preparations for the wedding, so long delayed, have resumed, and the day itself had finally come. At the apex of the ceremony, Sophitia and Rothion met with Cassandra and announced that they wished for their first child to be named by her, to which she felt greatly honored.
