Another MoD Harry dimension-travel fic! An accident dumps Hadria into an alternate universe where Fantastic Beasts series actually took place. Now, she has to deal with a Dark Lord and also make sure she doesn't accidentally end up helping him. Oh, and the Grindelwald from her universe is bound to be looking for her. Throw in some shenanigans, a very exasperated Dark Lord, a freaked out hellhound, and some demon summoning to make the dimension travel more entertaining. Cross-posted on AO3. Inspired by the fic 'Danse Macabre' by RareAvian.
