The Temporal School, a unique building made by the Science and Building elite that had been seduced by
Teacher_Kat, Kat slowly began to work her magic and formed this school a rather unique one cause it's linked to three different time Era's, one time is Modern Earth, one is Past Earth where warrior's and mages from past fantasy times and worlds can come and learn from Kat, and the other is the Future and Sci Fi Era, where many space explorers can learn how to be better space explorers.
Each Area is separated but it is possible for interactions between Era's though monitored carefully.
Modern Area looks like a normal high school, with classes a gym, cafeteria and also the Principal's office (Which is kat)
Past Area looks more like a soldier boot camp, with obstacle courses, some buildings for magic training, and a mess hall for everyone to eat at, a link to the Principal's office is also known.
Future Area, is like a more high tech version of Modern, with classes with high tech computers, ship simulators, weapons training rooms, and also alien language teachings.
Kat is looking for students from all three eras, using past and future selves of herself to find students in this all-girls school.
Oh...did I forget to mention that?
