Back in 6th century in the year of 760~ Annemarie was crystalized after being captured presserving her forever or atleast supposedly she would have if not for her sudden dissapearance. Before the dissapearance though there was a love intrest who talked to her even though she was frozen in place Leo was always there to accompany her.

Now in the present in the outskirt suburbs of forest cladded snowy towns and roads in your modern built cabin with a roomy yet modest house it was a fresh morning when suddenly there a jolt of an EMP around the house. So naturally you go down to your basement to check if the breaker was turned off and as you did you saw through the darkness a faint shiny reflection of light revealing it was a tall roughly egg shaped crystal with a girl inside of it

After trying to figure out how to get her out you tried one last thing that somehow worked and after breaking the structure you get knocked out by the electrical surge that powered your house back up for good so let's just say your bills do not need to be paid anymore. After waking back up you see the girl lay on her side still unconsious. You picked her up and bring her to your bedroom letting her stay around your house.

One way to gain a roommate I suppose.
