Information about the series
Yu-Gi-Oh! is a Japanese anime that belongs to Kazuki Takahashi, and it played for many, many seasons, generating a spin-off series, which is currently playing.
Yugi Muto, the main character, is a sweet kid who lives with his grandpa above his game shop. The shop specializes in a card game called Duel Monsters, where people collect an assortment of monster, effects, and trap cards to duel with other opponents for their strongest monster card. Yugi's grandpa is also an archaeologist who brought back an artifact called a Millennium Puzzle from Egypt. Yugi spent many nights trying to put it together. When he finally did, he inadvertently released the spirit of a long dead pharaoh, and his life was never the same...
The pharaoh, initially referred to as Yami Yugi (Yami meaning dark) for his dark personality yet physical similarity to Yugi, would occasionally take over Yugi, possessing him, especially when Yugi was in trouble.
In the first season aired in the U.S., Yugi is trapped into dueling another teenager at school, Seto Kaiba, for the title of Duel Monsters champion. In his dire situation, Yami took over, sensed there was a darkness in the Kaiba, and banished it, simultaneously winning the game. Back at the game shop, Yugi receives a video from a man named Pegasus. When Yugi played the tape, everyone else in the room was frozen in time, and Yugi was forced to play Duel Monsters again; but at the end, Pegasus used another Millennium item, the Millennium Eye, to take his grandpa's soul. In order to get it back, Yugi had to journey to his island and duel other Duel Monsters champions in order to eventually duel against Pegasus and win back his grandpa's soul.
At one point, in the episode "Give Up the Ghost," Yugi finds himself dueling Kaiba once again, but Yami realizes it is in fact the dark spirit he'd banished from Kaiba that Pegasus had somehow summoned. Yami banishes it once again and warns Pegasus that he's coming for him.
Later in the season, Yugi discovers that there are seven Millennium items - puzzle, eye, ring, scale, key, necklace, and rod. Each item has its own magical abilities and originated from ancient Egypt. The Ring found its way into the hands of another friend of Yugi's, Bakura, and like Yugi's Puzzle, it also possessed an ancient spirit, one intent on collecting all the Millennium Items.
Later seasons revealed more of Yami Yugi's past as well as the current owners of the Necklace and Rod (a mysterious figure named Shadi held the Scale and Key). A woman named Ishizu used her Necklace to show Kaiba a glimpse into an ancient past that suggested he (as the keeper of the Rod) and Yugi had a very long history of being rivals. Her brother, Marik, used the Rod to control a group of people called the Rare Hunters in order to exact his revenge on the pharaoh. When the evil spirit that had taken over Marik was defeated, Ishizu and her brother gave the Necklace and Rod to Yugi and Kaiba.
Yami Bakura, as the spirit of the Ring is sometimes referred to, was revealed to be a thief from a family of thieves, who the pharaoh wiped out. In my series, partly influenced by Vathara, Yami Bakura sought the Millennium Items not to take over the world but to avenge his family. He has a lot of pent-up anger, but the real Bakura, like Yugi, holds the key to helping him see past that to the greater good.
Also, we know from the series that Téa and Yami Yugi had an attraction to one another, but the creators made it a doomed relationship. In ancient Egypt, pharaohs and priests were very close, sometimes they would even marry. Priestesses in particular made dancing as part of their rituals, and we know from the series Téa is a dancer. The Puzzle and Ring had spirits in them that only awakened in the hands of their reincarnations. Who's to say the same can't happen with any of the other items? That's the premise for my first story, "Dark Magic Rising."
I haven't decided exactly how I'm going to continue the series, but it'll probably be greatly influenced by actual ancient Egyptian philosophies and practices, somewhat akin to the Yu-Gi-Oh! movie, and pull a lot from the U.S. first season (there was a season before that in Japan) - I preferred Kaiba when he was wearing green and purple.
