(Harry Potter Crossover) Across Time

Blurb: A pair of twin siblings, alike in appearance but bearing different surnames, appear in the past. They claim to come from the future, having crossed through time and space to this era by accident. They arrive bearing hope. Their many mysteries and secrets leave everyone baffled, but they also bring hope of defeating the darkness. What is their true purpose? Will the future and the past ever meet? Can the light defeat the darkness? And what secrets does the future conceal? P.S. Updates are irregular and chapters aren't long. It will probably be medium to long in length~ P.P.S.
