The Unknown/ Loki Laufeyson

Freya wakes up on a bridge in the colors of the rainbow, through which you can see, without any memory of who she is or how she ended up here, here on Asgard.

She is found by a few members of the Palace Guard and brought to the palace, and she is brought before Odin, who decides to lock her up in a cell until he knows who she is, why she is here, where she comes from, and what her intentions are.

But Freya attracts the attention of Odin and Freya's two children, of Thor, the god of thunder, and of Loki, the god of mischief. And they, too, want to learn more about Freya and want to get her out of that cell, because they are not satisfied with their father, for he thinks she is a threat. Freya doesn't know what to do, because there is just one big gaping black hole in her head where her memories have been removed, and it is driving her crazy, but fortunately it is not too lonely, with Thor and Loki by her side trying to help her, but the deeper they dig for information, the crazier it gets and Freya begins to doubt whether she still wants to find out who she once was.
