Two Reincarnated

In an unknown universe there rayed a world called Avallon, it was created by a once powerful god who lost everything to a war among the gods. At least that's how the story was supposed to go but no war took place among the gods in this story and the once powerful god just got his powers locked away by an even greater god who ruled over all the gods. But this once powerful god had left a child who now is desperate to bring her father back no matter what it takes, but in doing so she managed to reincarnate someone who had the same presence as her father, but this individual had possessed two souls who died at the same time in their old life and ended up being reincarnated in the same body without knowing it. One of these individuals has no memories making him think he is the same person as the other. Now they have to live in the same body while the child of the once powerful god tries to find a way to awaken her father and getting lid of the two.
