#i used to have a design for the vesel but i have no idea which book I've hid it in

Au, where the gods decide that both Atem and Bakura are equally guilty, and instead of throwing them to Ammit, they lock them in a clay vessel together. After some time, the vessel gets wakened and released from the afterlife into the mortal world by Set for lols. Now aware, Atem and Bakura's souls are intermingling with one another and at constant odds. They're both incredibly self-destructive, albeit in different ways, and they are equally bad at taking care of the body.

They probably end up in Japan and meet the Yu-gang at one point, but Bakura is constantly sabotaging Atem and pilots the vessel away from them. Atem's sad and angry, Bakura's sad and angry, and they are just generally not having a good time. Sometimes, their souls get too close together and merge a little, and it's confusing and painful for both of them.

Eventually, Malik will come into the picture and offer them his and his other self's expertise on Atem's and Bakura's situation. I'm not sure how this au would end, but one of the options is Atem and Bakura's consciousnesses fully merging and becoming a newish entity. (Steven Universe fusion go! XD) Another option is the vessel being successfully destroyed, and they just kind of stick around on earth as spirits or they return to the afterlife with an inseparable bond and get judged again.
