Nice! Will there be a sequel?

This is brilliant! It explains how Yami got his Old Vindictive Magician card and lets us know what really happened to Pandora... and Mahaado can be pretty seductive and sly.

Ugly people can angst! And Mahaado was acting seductive, wasn't he, feeding Yami fruit and wine? And it turned Pandora on? And Mahaado explained that Duel Monsters come from human souls to Pandora. Was that smart? Or was he implying that he could turn Pandora into a Duel Monster like you said in the first chapter?

All right! Love this part, because Yami proves that he cares for Mahaado as much as the Dark Magician loves him

“He deserves to suffer, for what he did to you.”

Mahaado blinked. “To me? You were the one he was trying to kill, my Pharaoh.”

“But you saved my life.” Yami got up from the table and walked over to where Mahaado was leaning against the window. “My most powerful monster… and the most loyal of all…”

“Ah…”

“You shattered your soul to save me.” Yami smirked.

“I am yours, my Pharaoh. Spirit and soul…”

“And body?” Yami grinned.

“That as well, should you desire it, my Pharaoh?” Mahaado purred.

Yami laughed, and dragged Mahaado down into a kiss.

... I guess it would be OOC if Yami said he wanted to be cuddled. But Pandora is an idiot! Throwing a filled chamber pot out the window into a bustling city full of monsters is not a good idea!

I'm not sure Pandora deserves a happy ending, although it would be funny to see how Kaiba's monsters deal with him. And Mahaado is the first person who has both ba and ka in the Shadow Realm, right? Unless the spirits of Kuru Eruna are also there... So that would make Mahaado the first child of the Shadow Realm...

Ooh! I like it! But you spelled 'heals' instead of 'heels' in love when you mentioned Yugi and Anzu. I always thought Mahaado was a nice person, at least he's very loyal to Yami and of course he is the Dark Magician... How can Pandora have a pure heart? Is he pure because he is insane?

They materialized in a castle with a distinctly Egyptian theme on the inside, and Yami heartily approved. It was much like home, but then again, Mahaado, reminded him of home.
He honestly had not known about his Dark Magician’s humanity until after the duel with Pandora. They had been …Well, as he often sought the Dark Magician out for comfort. That was one thing Yuugi could not grant him.

That … he hadn’t known his Dark Magician could speak, but they had both been stressed after the Duel – who wouldn’t be – and, perhaps neither of them had realized the impact of the truth when Mahaado had called him Pharaoh.

I love these parts!
