Siegfried had done the originally thought impossible. He finally defeated the Azure Knight, Nightmare after so long. Upon the death of Nightmare, Soul Edge simply shattered in pieces. Fragments of the cursed sword were scattered across the tower's floor. The evil that plagued his life for many years was now dead.
Finally, he would be forgiven for his sins.
Ice began to crystallize over Nightmare's body, forever entrapping in him in a prison that not even Soul Edge could escape from. As Siegfried began to walk away, he was stopped by an unfamiliar voice.
"You are not done yet." He spoke. "There is still so much more for you do."
Siegfried quickly turned, raising his blade in defense. He was then met face-to-face with the ancient Hero King, Algol. Adorned in scale-like armor, in one of his clawed hands were the fragments of Soul Edge. He beckoned to Soul Calibur as the blade flew from Siegfried hands into Algol's. He then completely shattered it with his power before turning away from the holy knight.
Both his hands began to glow, blinding Siegfried as he was enveloped in a blinding light. As he awoke seemingly many hours later, Siegfried seemed to be in a very bright-colored town unlike any village he had seen before.
Many curious, colorful horse-like creatures quickly surrounded him. Much to his surprise, they could speak intelligently. One particular, purple creature cautiously walked up to the tall man and simply asked one question, one that would forever change Equestria.
"Who are you?"
