My mate from another time

The universe was full of mystery. If you think that it's only about the world or the Earth, that was a big mistake because the universe has a lot of parallels and in every dimension, there was another world. And that's when this whole thing started.
Centuries ago, when the royal family was assassinated by Aceller, the next alpha of the kingdom of Ice, an evil, selfish, arrogant, murderous half-brother of General Erox Lander, Andrews. He is a very quiet and devoted guy at work. And he came from the fiery kingdom. This dimension has four kingdoms. Fire, ice, water, and air.
Aceller, or Ace, thinks that no one sees him when he kills the queen and the king. But the truth is, someone saw him that night, and it was none other than the princess.
Princess Margaret, who came from the fire kingdom, was a beautiful, kind, naive girl. And the only witness, aside from the magic ring that came from the king, is the magic ring. That ring is called magical because it can record the whole life of the last owner. The princess had no idea and was so very terrified that night. Because of that, she decided to escape and sneak to another dimension. which she never knew. It was the present, meaning whoever crossed the portal would travel through time.
The portal was located in the deepest part of the ocean.
But General Erox Lander, Andrews, They followed her, but in the middle of travelling, they didn't know that in the future there would be another Margaret and Erox.
What they didn't know is that in the future, there will be another soul that looks exactly like them, and they will also go into the ocean.
