Seto felt himself flying toward what looked to be an ancient city. And then, just as he thought he was going to crash onto the desert sands, he gently hovered above them, and saw what appeared to be an ancient version of himself. An older man sporting the millennium eye spoke to this look alike.
"Seto! Accept your Fate! Your Fate of the Pharaoh granted by me is Light and Shadow. Awaken to receive the power of the Dark and lead the world into a new age! Seto! You shall become the King and this land shall be yours to rule!"
The ancient version of him looked dazed. "Where is this...? Ah! Aknadin!"
"Look closely, Seto! With the new God, you shall hold the proof that you are the new Pharaoh! And that holder is heading over here!" He watched his ancient self turn to where Aknadin pointed and gasped in shock.
"Kisara!"
At his wife's name, Seto's eyes grew wide. He felt himself growing short of breath as the anxiety overtook his chest. "Seto! Your Fate is to become the new King!" Aknadin laughed. "It came. The holder of the White Dragon. Seto, you shall be granted the proof that you are the King."
Kisara ran up to Priest Seto's side, warning him not to listen to him. But the earth started shaking, and Aknadin announced Zorc's resurrection. Kaiba watched the dark one appear. Aknadin, who was now one with Zorc, ordered Seto to kill Kisara. Kaiba cringed at the words in disbelief.
Priest Seto spoke again. "Aknadin! Even if thou are my father, I won't sell my soul to the Dark! Let's go, Kisara!" He said, starting to leave with her.
"Seto! It is not possible for you to run from our set Fates!" Shouted Aknadin.
It jarred the memory of Ishizu's words loose in his own mind. "So you see, Kaiba, it was no coincidence that you met and married Kisara. You were destined to come together from the beginning. And now you must come together once more to defeat the new holder of the millennium eye."
He realized that he was seeing the past battle between the rod and the eye.
He watched as Aknadin tried to capture the two of them and How his wife's past incarnation fought against her oppressor. Even in an ancient form, she was protective of him. His counterpart was frantic, and Kaiba could only wonder what Pegasus was thinking of this little exchange.
"Stop, Kisara! You'll run out of BA!"
"It does not matter."
"What?"
"However... Seto... I shall protect thou from harm."
"Kisara...!"
Aknadin lost his patience. "What are you doing, Seto? Kill this girl and acquire the power of the White Dragon! Then, devote that power to Zorc and become the Dark King!"
"Thou are wrong! Aknadin: what logic is there to a world of Dark ruled by Zorc? Since I met Kisara, I realized how much of the world was Dark and dry. And the solution to make this Dark disappear is through this light called 'love'."
"Seto...!" She said, smiling.
"Foolish! And to think that you could surpass the loss which afflicted me!" Aknadin thundered.
"Kisara and I are not thy tools for revenge! The father I used to be proud of died long ago in the battlefield!"
"Seto!" Aknadin cried, enraged. He fired an energy blast at his son, and Kaiba watched as Kisara threw herself in front of him to save him. The image of her lying on the ground dead would be permanently branded into his memory. Even as a hallucination, it was too much. The Blue Eyes White Dragon was sealed into the stone tablet.
He watched his ancient counterpart kill his father, but couldn't do so before he took control of his mind. The scene brought back memories of Gozaburo Kaiba's own unsuccessful attempts to control him, and he had a gut feeling that this wouldn't last too long. The pharaoh, who looked and sounded so much like Yugi that Pegasus and himself shared a look, came to get his faithful priest, but Instead found another enemy awaiting him.
Then, an ancient duel began. The Dark Magician and Blue Eyes White Dragon battled one another. Kaiba realized that since the spirits of Priest Seto and Aknadin were merged together, their magic was twice as powerful. His Blue-Eyes White Dragon's Burst Stream of Destruction defeated Dark Magician's Magic Wave. The Dark Magician was destroyed, and The Pharaoh lost part of his life energy.
From inside of Priest Seto, Aknadin orders the Blue-Eyes White Dragon to attack the Pharaoh, but deep inside of his mind Priest Seto was resisting Aknadin's control. It would not bend to his will. Priest Seto murmured Kisara's name, And then suddenly the Blue-Eyes on the outside disintegrates and reappeared inside Seto's mind, breaking Aknadin's control over Seto. Aknadin's spirit was defeated and vanished. Inside his mind, Kisara spoke.
"Seto. Thou soul is no longer imprisoned by the Dark."
Kaiba watched his counterpart come to and call out Kisara's name in a broken tone. He watched him rush to her body, picking her up into his arms, begging her to wake up. It was precisely what he himself had had the urge to do when he saw her die in this vision. When his counterpart realized that she wouldn't wake up, he cradled her body to his chest and fell to his knees, sobbing as he held her up to the Blue-Eyes tablet. It was all he had left of her. And that's when Kaiba remembered that he had seen this exact scene before. Only once, in his battle with Ishizu. He felt it was important. That it meant something to see this, and the desperate need to figure out what it was made itself known. But before he could start getting answers, he was being sucked up into the white light from whence he came.
He woke up on the floor of the Kaibadome, back home once again.
