A New Sort of Magic (Marauders Era)

Four siblings from a very mysterious and secret wizarding academy in India transfer to Hogwarts as exchange students.
Outside, the battle between Light and Dark is slowly growing and beginning to rage.
A prophecy has been told.
The future is seen.
A new kind of foreign magic is unfolded.
The four siblings, young and carefree, in the eyes of other students, shoulder the heavy burden of undoing the damage done ten centuries ago. Will they succeed? Will families meant to be broken remain whole? Will children meant to be orphaned be able to keep their parents? Will people who are misunderstood as evil be able to keep their good name?
